Player source code
now that it is Christmas and other have give things to the community, i thought that i all will add to that, so i been fighting to get this little program finish.
i have add mouse control to make it easier to control, but that was not so simple and meant that i had to redo big parts of the program.
so there can very well be some bugs in it, i have not tested it on real hardware, mine is stash away.
it should works under STeem.
know bug, if switching to Drive A/B and there is no disk in, the program will come with a standard dialogue box and hang.
THX to the people that help me tested earlier versions of the program
the rar archive contain a floppy disk version and a HD version.

a little info about the program.
YMT files are like the YM/AY files.
Music files where you sampled data from the sound chip register (YM2149/AY8910) in a certain interval, instead of having a dedicate player.
up to now (to my knowledge), there have only been YM/AY player that could play tune/score files, that was sampled at 50HZ, but the YMT player can play files up to 300hz (there are some 50hz+ tunes/scores include in the examples)
the advantaged of AY/YM/YMT format, is that to replay these tunes/scores cost very little CPU power, so if you need a lot power for a eg. a 3D demo,
when it could be a wise choice to use it, because it leaves most of the CPU power for 3D calculations and the graphic etc.
and the disadvantaged is that it use a lot of memory, and also that it is nearly impossible to make a routine that can capture and use the SID sound and Samples etc.
it is also why those files need to be hand made, that is the reason why YMT-Player only support pure YM2149 sound.
Merry Christmas all
and may 2015 be a good Atari year
