KOF: Battle de Paradise

[Loïc]

Anyone have ever tried KOF: Battle de Paradise with neopop ?
At my first try, the emulator crashed the game after a few rounds :

Code:

Invalid register code used.
Stopped due to instruction
   20FFFF: ADC WA,(1--(null))      "D4 C0 90"

That's the first time I encounter such error in neopop. Does the game have known issues ?

Nope, In my case I don't use NeoPop few months ago. Actually I use EmuHawk, works perfectly for NeoGeo Pocket (sound and graphics)

Loïc, I wonder if there is something wrong with the ROM you are trying to load.

The fact is that the game crashed after a few turns. It's no big deal.
It can be a dump issue, or a rare game bug (the function that crashed is called really often. The 0xFFFF is supposed to be a computed value but obviously, 0x20FFFF is a data address)

I'll try to compare the dump with the one I did

Now that I think about it, another guy asked me about this before. He said it crashed on emu, and he wanted to know if it would work fine on hardware. It did. I think it's not a dump issue. That makes me think it's a NeoPop problem.

After some more tests, it must be a neopop issue.
Here's the code that leads to emulator crash :
[code]
0x200BC8: LD XWA,0
0x200BCA: ADD XWA,(0x4020)
0x200BCE: CALL NZ,XWA
[\code]

The value at 0x4020 is sometimes wrong and different than zero.
