Pocket Sap Plajer will be a small pocket device that could play ATARI modules/songs. Actualy, most of those songs are converted to *.sap format (sap file includes module and player in 6502-machine-code), so I will use final version sap files. Device will emulate 6502 uP along with POKEY chip, basing on sap-library.
Remember, all suggestions, comments, critics and help are wanted. I would appreciate all help mailed!

- After long time, the project is comming to light again. As for now
there are powers again to think about these things ;)
Device will have to emulate 6502 atari cpu and emulate POKEY sound generation in real time. While basic MCS51 seems to be too slow for this puropse and more powerful versions from Dallas are more expensive, MSP430 from texas instruments seems to be good candidate to perform this tasks easily. What is more, it has built in bootloader, so it gives end-user ability of firmware upgrade.
- We have players of MPT, MPT2 and CMC modules
- We have QuickAsembler with documentation
- I'm learning 6502 asm :)
- I know how the POKEY chip works (thanks to marok!)
- I need to rewrite song palyers attechet to each sap file, from 6502 assembler to mcs'51 assembler
- I'm looking for 6502 assembler documentation. I also need 6502 dissasembler. HELP!
