Cool! That sped up the spinning wireframe head in the intro which was quite demanding before.

Re: upd7725 overflow (attn: byuu)
SGN is used twice by the DSP1, for op02 (Projection Parameter Setting) and for op06 (Object Projection Calculation). The result doesn't seem to be discarded.

Re: Detecting 1CHIP consoles in software (maybe)
I just added some additional columns to my sheet : (1) result of the Burn-In Test (2) results for the SMP Test register 0A-FA. All of them seem to be crashing on 8A. One is even crashing on 0A, but that one seems to be broken as the Burn-In Test shows a failure on "DMA", "VRAM Low&quo...

Re: Detecting 1CHIP consoles in software (maybe)
That'd only explain small differences of up to +-0x10. 0x1000 -> 0xB000 cannot be explained by that.tepples wrote:Does the result depend on the ratio between the CPU/PPU clock crystal and the (less accurate) audio subsystem oscillator? Because the latter can be off by up to half a percent.

Re: Detecting 1CHIP consoles in software (maybe)
Seems to work for the Jr.
But I have some PAL consoles where some non-1CHIP are classified as 1CHIP.
Here are the values for the 1CHIP
1049
114e
145e
1977
and for the non-1CHIP
1041
1146
1453
196A

Re: Detecting 1CHIP consoles in software (maybe)
I tested it on my SNES Jr. with my SD2SNES and for some reason it says "Lame emulator detected" 
This is also shown with my 1CHIP PAL-SNES. The non-1CHIP versions seem to be detected correctly.

And proper OP1E support for SD Gundam GX should at least get the game fully playable, right? If someone needs help converting the Gundam X routines from 65816 to C, I can lend a hand there. We need more OPs, that aren't used in the available logs, to get the battles right. Most of the failures with...

The $1E command is still not bit perfect to Overload's DSP3 log. Some commands that are used during battles don't show up in the log. I fixed $1E in the current ZSNES tree, so it doesn't crash when the computer does a turn but it's still not bit perfect. I uploaded the current dsp3 source code to r...
