That gif I've posted is the white screen I'm getting. Can't you see it?

the issue is not the image, its that you are writting flash comm commands to the gdrom port, this is confusing MODE.

We would like to add filesystem access commands to MODE so you would be able to read/write data from the SD/HDD (so high scores and settings could be changed and stored into the SD or HDD filesystem)

This is the required fix for MODE :

track04.iso vs TRACK04_ORIGINAL.ISO

00113262: 09 11
00113263: 00 20
0011326A: 09 21
0011326B: 00 21
00113274: 09 01
00113275: 00 22
0011327A: 09 31
0011327B: 00 20
00113314: 09 CA
00113315: 00 8B

Thanks BmNT, this fix worked!

These changes work on MODE

I did not notice this function, in fact, you just need to disable it

We are going to add functions to MODE so you can bring back the test menu, store settings, keep per game sram on the filesystem


Open File (for read or write)
Read data from offset (2048 bytes)
write data to offset (2048 bytes)

we will make some library, or asm code so you can use them
but that will need new firmware

BTW thanks for your awesome work
