Not sure if this is a valid place for this question... please move or delete if not applicable.
Is RAM_COUNT (GFX_POLYGON_RAM_USAGE, GFX_VERTEX_RAM_USAGE) supported in no$gba? I can't seem to find an answer to this anywhere. I use these values in a few places and they work as expected on the hardware. However, they're always 0 in this emulator.
I noticed that iDeaS now emulates VERTEX_RAM, but I just can't seem to get my rom to work on this emu at all (I could be doing something stupid though).

Can you send me your roms? with source?

You can find the rom inside the .zip file on www.daftcode.net
I should note that I use v2 of Noda's EFS lib too (the Nitro FS stuff). I'm thinking the emu is fine, but somehow I might be messing up somewhere with DLDIing and the R4 option of the emu.

I found out what was preventing it from running on iDeaS. I use the other cache algo in my rom. I took the following out and it now loads:
| Code: |
#ifdef C_CACHERR
__asm("mrc p15, 0, r7, c1, c0, 0");
__asm("mov r6, #0x4000");
__asm("orr r8, r7, r6");
__asm("mcr p15, 0, r8, c1, c0, 0");
#endif

but this code disable ITCM and DTCM.

Geez, I hope not! I could be messing something up (I'm not great at asm), but from my testing the flag gets changed to the round-robin cache algo only. A lot of my functions are currently sitting in ITCM so if I was disabling L2 wouldn't that cause nothing but problems/errors for me?

Excume in my emu that code disabled ITCM and DTCM on real DS you enable/disable the chache managment algorithm.

That's the problem. Try loading the .ds.gba in iDeaS, that way EFS will use GBA ROM access mode. I could never get EFS DLDI mode to work in iDeaS.

iDeaS loads it fine with EFS/DLDI. It just wasn't working initially because of a change to the CP15 coprocessor.
