Re: Blargg apu_tes.nes 2-len_table failed test 2 of 8

Yeah i remember failing that test. Basically you need to copy the values from the wiki. if those values doesn't make your emulator pass the test test, then something is wrong with your implementation. Log how the length counter is decremented and maybe you will find some hints there. Myself I had A ...

Re: Battletoads lvl 2 and Megaman 5 fixed for O-Nes-Sama

Again, everybody feel free to correct me if i'm wrong. @Zepper I think it depends totally on how your emulator works, specially how you programmed the synchronization between PPU and CPU. At least for us, the scanline starts from tick 0 as you do too. Because how the synchronization works in our emu...

Re: Battletoads lvl 2 and Megaman 5 fixed for O-Nes-Sama

@zeroone We have been trying test ROMs and everything is passing, except for the ones that test not-yet-implemented features, (apu, sprite overflow, unofficial opcodes). Basically tests that were passing are still passing. @zepper I tried that game and the adjustment fix that game for us, now the ga...

Battletoads lvl 2 and Megaman 5 fixed for O-Nes-Sama

Hello guys! I hope I have some good news here! We finally managed to fix Battletoads level 2 and Megaman 5 issues with our emulator! Just yesterday Foomarumota and myself got together to check a "simple" issue with Megaman 5 that was causing a shaking bar when selecting a stage, we thought it was go...

Re: G.I. Joe (U) emulation problems

@koitsu I read both wiki articles and i couldn't find an explicit mention to the $2001 or disabling/enabling/checking "show sprites". So according to what I understood is that, at the beginning the sprite evaluation set everything to $FF and then when "Sprites found to be within range" happens that ...

Re: G.I. Joe (U) emulation problems

Hello guys, thanks for all your support! We found what was the cause of all this. I hope this thread would help newcomers to find what is wrong with their emulators! The OAMs fetches were not working when the OAMs were disabled . So we didn't see it when running other games, and tests would pass, an...

Re: FineX, FineY and zero hit

@Zepper
Sorry for the misunderstanding, we pass suppression test, what we are not passing is 07-NMI_on_timing test.


Wow! I wasn't expecting this! :shock: Very interesting...
What about Nestopia?? I tested both bart and battletoads and both does works as expected.

Re: FineX, FineY and zero hit

Hello guys, thank you for all the support so far! we were checking battletoads and it does hangs sporadically using whatever delay value. So we will spend some time to debug it. (in fact, program the save state module, make the debugger capable to debug this, and check everything, cpu and ppu) :wink...

Thanks for the quick reply Tepples! I read it at the very moment you posted it, but I didn't understand it, so that's why it took me so long to reply, sorry.
