Some notes from diffing the two NANDs: * EUR has `rw/sys/SecureInfo_A`; USA has `rw/sys/SecureInfo_B`. Not sure if this makes a real difference. * The region code value at 0x100 is...

The commands aren't detailed in the SDK, but it might be possible to reverse-engineer commands from the IS-NITRO-DEBUGGER software. Do note that the commands sent by ISND are not the...

GBATEK lists three sets of Blowfish keys for KEY1 initialization: * NDS (ARM7 ROM):...

I can get a dump of Firmware 56 for both 64M and 128M. (I have RVT-R Reader, RVT-H Reader, and NDEV systems available.) I believe they're also available in SDKs...

I completely forgot about this. I'll get the debug IOSes from the SDKs tomorrow, though I can't post them here for obvious reasons. Debug IOS WADs are signed using the...

Not sure why it'd remove the last 4 bytes. Can you post the filename and SHA-1 hash of one of the WAD files where that happens?

Taking a look at jctool.cpp, it seems that UI code is intermixed with I/O code. Probably the best thing to do first is split out the I/O code into its...

I haven't really done much work on Gens/GS II recently, especially since emulators like genplus-gx and blastem have advanced significantly farther than Gens/GS II could ever hope to get. I...

Gens/GS II is currently in a not-very-good state (mostly because I can't figure out why the video keeps dropping frames even when CPU usage is low, while other emulators have...
