General Discussion / Re: Sega Game Gear Plug-in?
« on: 17/May/2016 07:42:33 AM »
So then If I just simply salvage the cartridge connector out of a broken Game Gear then I can just pop the SMS plug-in open and solder it in? Will this also work with the cartridge connector from the SGG's Game Genie or are the pins spaced differently between them?

General Discussion / Sega Game Gear Plug-in?
« on: 16/May/2016 09:18:25 PM »
So I bought the retrode 2 and all the available plug-ins that were available for purchase, and I have enjoyed using them greatly. However when I got my SMS plug-in I was disappointed to see that despite having been developed to also support SGG games as well that it only had a connector for SMS.

Frankly I don't really have very many SMS games, but I have a crate full of SGG games.

I know it is a fairly simple matter of salvaging an old SGG cartridge connector from either a broken SGG or a Game Genie for one and building a board since they have the same pinouts just in a different arrangement. However, I haven't built a board before so I was curious if anyone with more experience could build either an SGG plug-in or an adaptor I could use to plug my SGG cartridges into my SMS plug-in for me.

Honestly it is printing the board that is a pain in my ass. I don't mind salvaging connectors from dead consoles and accessories. I just can't etch a board worth shit and wouldn't know how to place an order for a custom printed board.

General Discussion / Well... Now what?

With production of the Retrode and it's adaptors halted indefinitely what are we to do? Are there others out there willing to or perhaps already producing Retrodes or Plug-in adaptors for sale? I fortunately already got my hands on a Retrode 2, Gameboy Plug-in, Nintendo 64 Plug-in, and Sega Master System Plugin so I am set on all of that. I know Matthias has posted schematics for other Plug-ins on the official site, but I know not everyone is up to the challenge of building their own. I would personally love to get my hands on Atari 2600, Nintendo Virtual Boy, Sega Game Gear, and other Plug-ins. I had hoped to just wait for them to come up for sale on Stoneagegamer.com, where I got the ones I presently have, but I guess that won't be happening now. I don't suppose anyone who knows a bit more than I do about printing and assembling circuit boards would be willing to build them for me?

General Discussion / Re: Emulators & Netplay

Thank you for the info. I found it very helpful. I realise the post has aged a bit, but I am still seeking what ever information I can find on the subject of getting my games to play online. Be it via Netplay or if they ever get that broadband adaptor emulation working on Null DC. It would be great to be able to play these games without the hassle of trying to organize a gathering for local multiplayer.

General Discussion / Re: How do you fix RGB shifting?

Not entirely sure because I am still a bit new to console repair, but my guess is go in and replace all the electrolytic capacitors in the system. They are past their expected lifespan by now anyway and are known to cause audio and video issues.

General Discussion / Damaged cartridge repair.
« on: 24/Apr/2014 03:20:11 AM »
I have an old Pokemon Blue game cartridge that developed problems a while back rendering it unplayable. I was able to copy my save file off of it and the save file was not corrupted so I know the SRAM chip in the cartridge is working fine though I cannot identify which of the 4 chips is the SRAM. Given that the SRAM is working correctly that leaves either the Memory Bank Controller or ROM chip itself as being the source of the problem and I was curious to see if perhapse there was a way to determine which one it is by examining the dump of the cartridge ROM.

If the MBC is damaged I can salvage a replacement from another cartridge. If the ROM chip is damaged I can salvage the SRAM and MBCor maybe even use the cartridge as my own dev cart by wiring in a removable EEPROM chip. Seems like a win/win either way. But how would I go about determining which chip is fried? I am leaning towards the ROM chip myself as the MBC was still used to access theSRAM and the problem did nit affect the SRAM.

The game does start and load correctly, but the moment you attempt to open any dialogue box or get into a fight it glitches up. Pokemon encounters begin to play odd noises and text becomes scrambled sprite tiles. If I could repair the cartridge I would like to. Anyone got any advice?

No I have not updated the firmware. Where do I find the latest version and the instructions for how to perform the update?

Come to think of it. I had to force the size on the games in copying too. I assume they must not contain header info regarding their size. I am not sure the sizes I got back from my research were right though. Could this issue be attributed to under dumping?

Support / Odd video issues on Master system games
« on: 06/Mar/2014 01:04:37 AM »
I am experiencing a problem with the video quality on my Sega Master System game dumps. Namely Gangster Town, R-type, and Zillion 2 (the only 3 SMS games I own). The issue I am having is that each game appears to have the entire game screen shifted slightly to the right leaving a gap (approx. 1/4-1/2 inch) between the left side of the monitor and the actual game display. This does not appear to happen with the game's title screen, however, but once in the actual gameplay it begins to do this. I was experiencing this issue on my Sega Genesis (through the Powerbase Converter), but not on my Sega Game Gear (via the Master Gear Converter). I originally believed the issue to be the result of a hardware problem with my Genesis since it plays properly on the Game Gear, but now that the emulators are doing the same thing I am not really sure what to think of it. Gangster Town show the problem the most out of the three as the background actually is in the correct position and only the foreground is out of place.

The only thing I can think of is that the capacitors on the board inside the cartridge themselves may have gone bad. That or there may be a problem with the actual ROM chips themselves. But I find it unlikely that all 3 ROM chips would experience the same problem in the same way, so I am leaning more towards the capacitors due to their age. Still Wouldn't hurt to get a second opinion to see if there may be another possibility that I have not yet considered.

I am really looking forward to getting this issue solved and getting these games working properly as I never actually owned a Sega Master System when I was a kid and I would love to start picking up more SMS games. I am also concerned that I may experience the same issue with my Sega Game Gear games once I finish building an attachment I was working on for my SMS plugin using parts pulled from a broken SGG Game Genie.

It is also worth noting I have been experiencing an odd problem with copying the SMS games with my retrode as well. It seems, once I hook everything up, if I go to copy and paste the game file from the retrode to my PC then it will give me an error message stating that the file cannot be found. However, if I first open the configuration file and save it before attempting to copy the game file then the game file will be copied as normal. I don't know if this may have any correlation, but I thought I would add it just in case.

Support / Cannot eject Retrode properly + configuration issue.
« on: 06/Jan/2014 12:07:37 AM »
I go to eject my Retrode and it keeps saying a program is still using it even though no programs are open. Also all of my emulators use save files using the extension ".SAV" The Retrode gives the files the extension ".SRM" and marks it read only. As a result if I try playing the game from the cartridge it will not load my save or be able to save to the cartridge. I have tried using the configuration settings but they keep reverting to default; though the configuration settings for forcing file size and cartridge type work. This has also made it more time consuming for me to restore backup saves or move emulator/edited saves to the cartridge as I now must manually rename the .SAV extension to .SRM and manually deselect the read only option on the cartridge's save file. It is not a serious problem, but since I often replace save batteries for other people and offer to restore their save when I am finished (for those who bring their game in before the battery is completely dead) or to recreate their save (to the best of my ability using save editors where possible) it does make the process take a little bit longer.

Support / SMS plug in and SGG compatibility
« on: 29/Dec/2013 07:54:08 AM »
Hello. I just got my hands on the Sega Master System plug-in adaptor for my Retrode and I had heard that even though it does not have a slot for Sega Game Gear games built in that it is still compatible with them and even has a spot for a Game Gear slot to be mounted on the Board if you have one. Seeing as how my Game Gear collection is considerably larger than my Master System collection I am quite interested in making this modification.

It seems to me that the most cost effective method available to me would be to salvage a slot from an existing device and I was thinking of taking one out of an old Game Gear Game Genie, but this leaves me questioning whether or not this part will fit properly. If anyone would happen to know I would greatly appreciate the info as it might save me from wasting $10 if the part won't fit.

Support / Re: Discerning cartridge file sizes.
« on: 07/Dec/2013 07:49:52 PM »
My concern about over dumping has nothing to do with functionality. I am aware that an overdumped game should work, but It will also take up additional space which can be wasteful on some smaller storage media. I already zip most of my files to conserve space because the phone I do much of my emulation on has a fairly limited storage capacity and I have hundreds of games to load up on it for dozens of platforms.

Support / Discerning cartridge file sizes.
« on: 05/Dec/2013 09:57:15 PM »
Previously I posted in regard to some GBA dumps of mine that were not working and with the help of Matthias learned it was due to the Retrode erroneously under dumping (failing to copy the entire game ROM) the game because it's automatic size detection came back with the wrong size.

This matter was solved by simply manually setting the Retrode to the correct size in it's configuration settings.

Matthias in this instance told me the correct sizes to set for, however, as this can happen again with other games in the future I would like to know how I can decern for myself what the correct file size is. Unfortunately ascertaining this information has proven to be somewhat more complex than a mere Google search as just about any search containing any word remotely related to ROMs only turns up sites hosting ROMs for download.

I do know that these ROMs do have information regarding their file size listed in their header, and that any partially successful dump should contain the header information so if anyone knows of any utilies for reading the header information or listing of correct file sizes posted out there I would find such information quite useful.

I just don't want to have to bother anyone with such questions again in the future. This way I can be more self sufficient in my backup efforts.

In addition to using this to correct under dumping I shall also be using it to check my files for signs of over dumping.

General Discussion / Emulators & Netplay
« on: 29/Nov/2013 04:07:59 PM »
Hello now that I have my retrode and have copied almost my entire game collection I am now turning my attention to what I can do with them. I have several emulators already and I have noticed many of them have a feature called Net play which is supposed to be able to enable online multiplayer by connecting and synchronizing two people's emulators. I do not download ROMs (as that would be illegal) so I have been unable to tinker with this before.

That said... I was wondering if anyone else here would mind sharing their experience on the following questions regarding Netplay:

What emulators/versions of said emulators do you find to have the most stable Netplay?
Where should I go to look for/set up matches?
About how stable (on a scale of 1-10 with 1 being unplayable and 10 being perfect) would you say the matches are?
Is there any other information pertaining to Netplay I may find useful?

I do not limit my emulation to just cartridge based systems so please do include information regarding Netplay for any system.

In addition to this it has come to my attention that there are still games for both the Sega Saturn and the Sega Dreamcast that can still be played online. Are there any emulators/versions of emulators which can support this connectivity (example: emulating the Dreamcast's Broadband or Dialup modems)?
