icbrkr Posted October 28, 2002 Share Posted October 28, 2002 I'm playing with the SAP program, and I'm very surprised how good many of these songs sound (almost as good as a SID chip ). Reading the FAQ, it states that it's emulating the POKEY chip, so I'm assuming that this same music could be used on a 5200. Now, how hard would it be to write an interrupt driven player for it?

Heaven/TQA Posted October 29, 2002 Share Posted October 29, 2002 well...i write this completly out of the blue... but i have somewhere the XASM source for taquart's music composing tool called theta music composer. the replay code could be adapted from atari800 to 5200... but as taquart guys use always high optimised code it could be not so easy (f.e. nasty 6502 adressing tricks) f.e. regarding adressing the soundchip hardware... another idea could be... try to extract the SAP player, load it into atari800win and try to disassemble the stuff...change the pokey registers and "incbin" the stuff into your code... an interrupt handler is in general not necessary except that the music routine is run every 60/50 frame... and if you know how to install a vbl on 5200 than that is it... (assuming that you don't want a atari800 music with digi voice...) hve Quote Link to comment Share on other sites More sharing options...

calamari Posted October 29, 2002 Share Posted October 29, 2002 I think Ronen Habot used SAP music in 5200 Castle Blast for a Pac-Man sound. He may be able to give you a few tips too. calamari Quote Link to comment Share on other sites More sharing options...
+Cafeman Posted October 29, 2002 Share Posted October 29, 2002 Yep, Ronen has a procedure narrative for how to extract the SAP tunes' data and put it into HEX format to put into your 5200 game. One of these days I must learn how to do it myself. Quote Link to comment Share on other sites More sharing options...
icbrkr Posted October 30, 2002 Author Share Posted October 30, 2002 I found his webpage and took a look at it... not too hard really at all to do, especially since he has a util to rip the header off the file. I'll have to do some playing to get it work right. Thanks again as always. Brian Quote Link to comment Share on other sites More sharing options...
