Yep, perfect, thank you very much. Sorry for the delay in responding.

Thanks for incorporating our changes. There's one error in `CartPhoenix::MapCart` -- it should be using `Page_Length` for the loop increments -- see https://github.com/ElectricMagic/AtariPP/commit/a5a1b4f989884259db494e7ec5902de17866a9f9 And there's an inconsequential fix at https://github.com/ElectricMagic/AtariPP/commit/2cdad907e3547925a76ee738e93c17fc21a519c5, where the enum should be `All` vs `Any`. https://github.com/ElectricMagic/AtariPP/commit/bf66e03e2a7eeae5d97a96021a9a83d055a499f8 lets us pass a hard-coded command line without nasty typecasts.

Which .a78 binary are you checking with? I haven't had any luck with the one with md5 hash 8137c820ccd9eb7a677287b44b50083a, which I edited the header of to indicate pokeys at $450 and $4000 (should cover the bases, attached) I did have a look at the sound effect .asm files, but I couldn't locate anything that looked like it was doing detection. Galaxian P450_P4000.A78

Great -- so `header[53] & 0x04` indicates pokey at $440, and `header[53] & 0x08` indicates ym2151 at $461/462.

Here it is playing in Argon: ByzexByTatqoo240Hz.aac

MAME currently uses the value 1 and 2 (thus bits 0 and 1) of 53 to indicate A78_ACTIVISION and A78_ABSOLUTE. Maybe we should use bits 2 and 3 for POKEY 440 and YM2151? Or perhaps leave that bottom nibble alone and use bits 6 and 7.

I'm working with @bhall408 on Argon, which is based on MAME for 7800 emulation. I took @rj1307's `outrunjazzed.a78` and changed the cart type field to $41, which would normally indicate a second pokey at $4000. I modified `a78_rom_p450_pokey_device` so that it's actually at $440. We're panning $450 mostly right and $440 mostly left, and it sounds really nice (see attached file). I wonder, is there a mechanism by which we can get the .a78 format extended to indicate that a cart expects to see a pokey at $440? AcidJazzedStereo.aac
