I try to keep different parts of the machine in separate logical "structures", in this case a source repository/folder.
Now the V30MZ cpu is not used in any other machine except the WonderSwan, but take the 6502 is used in _many_ machines so the exact same source code is used in a lot of my emulators without modifications. So in this case "core" is just something that is more or less pluggable into the other parts of the emulator, kind of like emulator cores in RA.
Neat! I think I get it now, just hearing the core terminology was confusing outside of RA; but just different emulated components (cpus in this case?) often get used across many machines I guess? And I take it you have some good emulations of commonly useful and powerful ones. Thanks for clearing that up.

Okay, so Im back! Got a question about the file too large error - I thought this might go away if I ran NitroSwan on my DSi in DSi mode, but I guess not, because now it just freezes on the "Please wait, loading" screen. I'm not sure if its a limitation of the software of if I have done something wrong? I've loaded in all the bioses I could find to see if that helped but still no dice. Most of the games don't load. If DSi mode doesn't do it, would a Lite with a ram expansion help? So far Im getting the same compatibility as I did with flashcarts

The graphics for "Hataraku Chocobo" were not displayed correctly and I was unable to continue the game.
Please fix this.

I compiled the latest version of NitroSwan (V6.5) and I too have a display problem with the English patched version, however, unlike NGPDS, I don't think @FluBBa has finished NitroSwan yet, compared to from what I have seen on Github, I believe that he is still working on it, so it is perhaps possible that this game will benefit from a better result in the future :)

Since which version is this? Is V0.5.2 ok but V0.6.0 is not?
After few tests, I can say the bug appears at the v0.6.0 to the v0.6.5, as you said, it works fine with the v0.5.2 with "allow refresh change : ON" & "CPU Speed Hacks : OFF" options

The problem was one of the two hardest things when coding (naming things and making a cache), will be solved soon.
Post automatically merged:

So I fixed the cache for most situations, but now it won't speed up games which use double buffered tile maps (like Hataraku Chocobo) but hopefully that won't matter on the DS.
  • Added saving of joypad layout.
  • Added extra RAM on 3DS.
  • Fixed cache bug in tile map rendering.
  • Fixed repeating sound DMA.
  • Fixed HyperVoice scaling/mode.
  • Fixed EEPROM handling a bit.
  • Fixed Quit Emulator when started from TWiLight.

What do you have in mind?

Use of extra ram and more powerful hardware has probably been done as much as possible for the DSi.

A 3DS port would be needed to use more ram for the few games that could use it. Yeah it may seem ridiculous to need a 3DS hardware but when certain Gameboy/Gameboy Color emulator got ported from the DS and DSI to to 3DS it improved a whole lot in speed compared to the DS/DSi version.

Is it possible to play this ONLY on the bottom screen for use in my GBA Macro (DS Lite with no top screen), I run GameYob this way for GBC emulation. Would be amazing.

The extra ram in 3DS is useable in NitroSwan (for Beatmania), though I haven't figure out how to enable cache for that RAM so it's really slow right now. I will try to make a real 3DS port some day to get a real software renderer to fix the last gfx glitches.
That would be amazing, we really need more 3DS emulators and the Wonderswan is a good candidate
