Support / N64 with SRAM lose save files after disconnecting.
« Last post by BKong on 22/Jun/2019 06:03:34 PM »
Hello everybody.

I have recently gotten a retrode 2 a few months ago, but I seem be having trouble with losing save data on N64 games that use SRAM. When initially connect the cartridge to my computer, the save data is there, and I'm even able to dump it and load it in project64 in most cases, but no matter what I do the save data is gone once I disconnect the device. I've tried other cartridges that use different save methods and they all seem to manage to retain their save data after using them with the retrode.
Here's what I've tried specifically so far:

SRAM:
Harvest Moon 64, Super Smash Bros, Mario Golf
I'm able to dump the save files from these cartridges and load them on Project64, but they always lose their data after disconnecting. They retain their save data otherwise, it only happens after connecting to the retrode.

4Kbit EEPROM:
Bomberman 64, Bomberman 64: Second Attack, Bomberman Hero, Mischief Makers
I'm able to dump the save files and load them on Project64. Save files were maintained after disconnection. In the case of Bomberman Hero and Mischief Makers, I was even able to write a different EEPROM file onto the cartridge and have them work on my N64 console.

16Kbit EEPROM:
Yoshi Story:
Dumped, loaded, and maintained save file no problem.

Flash:
Pokemon Snap and Majora's Mask
Haven't been able to get the save files to work on Project64 yet, so I don't know if the dumping actually worked, but these games at least kept their saves after disconnection.

I'm using FW .25a-beta.

Thanks in advance.

Stick with 5 V for Game Boy (Color) games. I just figured this out with Pokemon Pinball and Pokemon Blue.

I've seen some of you mention forcing a game to be a particular size. I'm testing Kingdom Hearts for the Game Boy Advance and it is showing as only 0 bytes, and obviously does not work. Any suggestions?  I don't know how to change a file size... or if that's even possible.
There's a configuration file on the retrode. It will have options you can change. You need to edit that. Also, keep in mind things like voltage of the system. While not all games may be picky, you may have to switch to 3.3V for some N64 and GBA games, but to 5V for other systems.

Just hooked my retrode2 up again today to try and dump my Perfect Dark copy, but for some reason it's only 8 mb and just doesn't wanna start. Am I missing some setting somewhere? I think this is the only game that I have that isn't dumped yet.
Did you set the system (n64) and size in the RETRODE.CFG file?

General Discussion / Support for NTT NDK10 SNES Controller?
« Last post by Duckers on 16/May/2019 05:01:32 AM »
Just wondering how hard it would be to get Retrode firmware support added for the NTT NDK10 SNES controller as documented here...

https://www.raphnet.net/divers/ntt_data_sfc_controller/index_en.php

Currently the light on the Retrode doesn't blink when the extra buttons are pressed, however the general SNES buttons appear to work okay.

Happy to help test!

Support / Can't eject Retrode from PC (Windows 7)
« Last post by Gladson on 16/May/2019 01:26:07 AM »
Whenever I finish using my Retrode I try to eject it (just like any other USB device) using either the USB icon by the Windows clock or by right-clicking the mapped unit and selecting "Eject", however, it fails anyway. "Error ejecting RETRODE (E)" is shown.

Is that normal? I'm making sure the led is not blinking when I pull the cable but it feels unsafe doing that nonetheless, I'm afraid I could corrupt something.

The voltage selection is crucial, just mind it.  The retrode 2 comes with a pamphlet of correct voltages.
.
I've experienced zero issues corrupting data on carts.
.
Upgrade firmware as the first step.
.
Pay attention to proper cart orientation.
.
I had to disassemble and clean/polish/restore most of my cartsfor proper reads.  I personally take out board, initially clean with 90% rubbing alchol, then polish with a white poly eraser.  After assembly hit the pins one time with a q-tip saturated with contact cleaner.    One backed up, I again took apart the carts, cleaned/restored the cases, and replaced old batteries with battery holders and fresh batteries.  Finnaly put into mylar bags with dessicant and o2 eaters.

I've started to research methods of backing up and restoring saves from all my retro systems when I discovered the Retrode, that would allow me to do that on many systems with a single piece of hardware, great tool. I just ordered the kit with all plug-ins from Dragonbox so I'm reading as much as I can about it before I start using it so I don't do anything wrong.

I've read about the voltage switch, that must be set to 3.3V when using N64/GBA carts and 5V otherwise. Is that correct? Is there any other systems that needs to be set to 3.3V? Even though GBA must be set to 3.3V should I use 5V for classic GB / Game Boy Color carts?

Other than changing the voltage switch is there anything else that should be changed when backing up/restoring saves from different systems? I plan on upgrading to 0.25a as soon as I get so I can start backing up not only SNES/Genesis saves from cartridges but also N64, Master System and classic Gameboy saves from their carts.

And finally, any other advice for a complete newbie? I really don't want to risk corrupt/delete saves from my cartridges when trying to backup them due to any kind of mistake.

By the way, let me take this opportunity to make a (probably) really dumb question: I see there is a "Retrode" and a "Retrode 2". What's the difference? I haven't seen any unboxing with "Retrode 2" written on the box, they're all like the following picture. Is that "Retrode 2" even though the box doesn't show it?

Would be great to see a few of these sold for people (like me) who have no skill in attaching the game gear cartridge slot to the master system adapter.

Same. I wish. I'd get one right away.
