GBA games nonfunctioning [SOLVED]

[billy.wade]

I'm having trouble emulating a few of my GBA games from the Retrode and its ROM dumps. All games are NTSC and function on a GBA SP. I emulate both from VisualBoy running in WINE and a PSP running gPSP Kai. If The Emulation King (Matthias) would like, I have copies of the ROMs, provided e-mailing zips of them for debug falls within the confines of US law.

Pokemon FireRed: Opening animation runs, but beyond that nothing.

Pokemon Emerald: Runs on PSP, white screens on computer.

The Chronicles of Narnia: The Lion, the Witch, and the Wardrobe: Blank white screen, crashes PSP.

Yu-Gi-Oh GX: Duel Academy: Blank white screen, leaves PSP running.

Please check to make sure the ROM sizes are correct.

If not, force the size in the Retrode config.

Do you know how to verify checksums? If so, please do (on the correct size ROMs).

If you do not know how do either, let me know and I will tell you.

[billy.wade]

I don't know how to do either, to be honest.

FireRed: 64/128 mbits

Narnia: 8/128 mbits

Duel Academy: 8/256 mbits

Emerald: Full size

Basically inorder to get fire red yo work you need to open Retrode.cfg in an editor like notepad++.

Scroll until you see
[forceSystem] auto
[forceSize] 16

Change both those values to
[forceSystem] gba
[forceSize] 16

Note you will note be able to retrieve the save data only the rom. If you wish to play other games you need to change the [forceSystem] back to auto.

I just tried it on my system to make sure I am telling you correctly and I was able to get to choose my first starter. What I  posted above is for Firered. Though is should work once you know the [forceSize] in MB.


Firered : 16
Emerald: 16
Yugioh : 32
Chronicles of Narnia : 16

Just use that datomatic.no-intro.org and convert it from bytes to MB

I tried to alter the values, and upon saving, I got alerted that there is no space left on the device and that the file would be truncated.

EDIT: when opened in Gparted, the Retrode is displayed as having 128MB unallocated. Should a partition be granted to it?

If you're under Linux (WINE?), your most convenient way of altering the config may go along the lines of:

echo "[configSetting] value" >> /path-to/retrode/RETRODE.CFG

The Retrode has exactly 2560 bytes of writable memory (the config file itself, plus some FAT entries). Everything else is a matter of pure imagination and part of why I'm so proud of the thing

[billy.wade]

It worked! Thank you, Matthias.

I would be proud, too, if I had built the greatest consumer emulation tool since the computer itself.

Thanks for confirming! Wish you a lot of fun with the gadget.
