I'll look into it, but I need some additional information:
  • Which firmware version have you been using when reading the GB camera save still worked?
  • Please take a look at the .gb file with a hex editor: What are the values at offsets 147 hex (327 dec) and 149 hex (329 dec) of the GB camera ROM?
  • What's the file name of the .gb / .sav file?
  • What's the size of the .gb file?
  • Do the first few hundred bytes from the start of the .gb file repeat at offset 4000 hex (16384 dec)?

I've replied in the newer thread at http://forum.retrode.org/index.php/topic,383.0.html

Support / Re: Cannot grab sram from Game Boy Camera
« on: 24/Nov/2017 01:37:22 AM »
I couldn't get the SRAM file at all from mine. Using the 0.20 Beta firmware that my Retrode 2 came with, I could only see a 1.2 megs "WMuzoysMur.gb" file on the Retrode. It works in 3 different Game Boy types, and I cleaned the contacts with alcohol first, then contact cleaner as a second pass, having removed the cartridge shell.

The "[forceSize]" configuration option you added is probably not going to change anything, as that's just for the ROM size, not the SRAM size.

It never worked for me, and it's the only version of the firmware that I ever used. Maybe someone else can help?

This is hexdump's output for those values:

What's the file name of the .gb / .sav file?

No .sav file, the ROM is "WMuzoysMur.gb".

What's the size of the .gb file?

The file is 1192960 bytes long.

No, here's about 10 lines of the stuff:

Just needs a nice sticker now :)

(I've made such a sticker for the SMS/GG combo, after cutting up a Megadrive case as well, I'll post it once I've actually printed it out for testing)

Bummer. Even Fedora 26 only has 4.11, and Debian-based distros are further behind. Linux Mint won't let you get 4.12 from the update manager, so you'd have to manually install it.

Fedora 26's current kernel is a 4.13 kernel. You can see the module right there, in F26's latest kernel update:

I guess I don't understand why a special driver is needed, though. I thought the Retrode displayed controllers as HID-compliant devices for the specific purpose of making sure that you wouldn't need a special driver to use them.

It shows up as a single joypad with tons of buttons without a driver, which works fine if you can remap all the buttons, but not easy to work with, and impossible to do in some games and emulators.

The driver splits it up into 4 separate joypads with nice names and a device for the SNES mouse if you have one, and want to use it for emulating Mario Paint, for maximum immersion :) Is that clearer than my previous comment?

Upgrade your kernel!

I wrote a driver for the Retrode which splits off the 4 joysticks into SNES/N64 and Megadrive pairs, along with understandable names. It's upstream now, but you can use this out-of-tree driver if you need:
https://github.com/hadess/retrode

I will not answer questions about the out-of-tree driver, as it's only there for my own development, and helping reviewers. Ask your distribution to add the Retrode driver to their kernel if you run into trouble with the out-of-tree driver.

HTH!

General Discussion / Re: Adaptors

Just wanted to add that the 32x while plugged into the retro gold genesis port will rip 32x games fine, ive had no problems with that.

If somebody wants to add to the list that 32X cartridges (I've only tested it with Star Wars Arcade mind!) can be rippped using a simple region converter. You can also take your Retrode or cartridge apart for it to physically fit in the Megadrive slot.

> @hadess whats wrong with just using that markiii to megadrive converter with the retrode? The schematic looks pretty straight forward so it should work.

Well, because it didn't work ;)

I should probably have added this information in my first post, but I had been putting off posting for so long, that I didn't even think to try and explain why I went down this path.

I have 2 cartridges that work out of the box with the adapter on my Megadrive II PAL:
- Enduro Racer (Mark III)
- Alex Kidd In Miracle World (Mark III)

Those 3 games will not boot without stack init. A trick that's mentioned on the Raphnet page is to swap a working cartridge quickly with a non-working one, while powered off. Another way, which I wouldn't recommend but works is to start the Megadrive with the adapter but not the cartridge, insert the cartridge and press Reset. Anyhoo, the 3 games:
- Alex Kidd BMX Trial (Mark III)
- Space Harrier 3D (Mark III/SMS)
- Opa Opa (Mark III/SMS)

All 5 of those are detected as 4 megs "GenericRomInSegaSlot.dat" dumps. Dumping the ROMs ends up in garbage.

There's a few active components on the Mark III/SMD adapter, where the Retrode SMS adapter has none.

Hope that clears any doubts about the reason why I'm asking ;)

(and if you want to share your pinout for the card reader, probably in a separate thread, it'd be appreciated!)

Hey!

I have a fully loaded Retrode 2, including the Master System adapter, but I've been buying a few Japanese Mark III/Master System games which I wanted to be able to dump.

There's a couple of threads already about various third-party adapters being tested, none working from what I can tell. So I thought I'd "make" my own. Here's my thinking, and do stop me if any of this sounds wrong.

1. Find the physical bits needed to connect everything. That was relatively easy. After spending a couple of hours (!) on electronics supply sites, the cheapest way to get a MegaDrive connector on one end, with a Mark III connector on the other is Raphnet's Mark III for Megadrive adapter:
http://www.raphnet-tech.com/products/brd_markIII_to_smd/index.php
and here are the schematics for it:
http://www.raphnet-tech.com/downloads/markIII_to_smd_schematic.png

2. Let's forget the above for a moment, and find out how the SMS adapter is pinned out. I found this:
http://consolingmyself.co.uk/post/18692678762/retrode-sms-gg-plug-in-adapter-pin-out
Is this still accurate? Let's assume it is and move on.

3. We need to find out what the differences are between the SMS and the Mark III pinouts. I found this on SMS Power:
http://www.smspower.org/Development/JapaneseSMSCartridge

And at this point I'm kind of stumped as to how to use all this information. I think I'm missing an "export SMS to Mark III diagram" somewhere. Ideally, it'd support Mark III and Japanese SMS games[1], but I already see some difference in wiring for some lines that the Retrode uses (though I could have had my numbers crossed).

Any ideas? Cheers

[1]: Bonus point if I can dump those 2 SG-1000 cartridges I have ;)
