What new.

Program is move from Beta to version 1.01

if the home folder contain a directory call 'SCORES' the path will be set to it.

if run from a hard drive the program will now use a ini file

bug fix:

If the music loop point was not set at the beginning, the music became messy, when it started over again. (it look like, that i accident have delete a line from the sources code without knowing it smiley )

Draging in the dir slider, could give 2 bombs when exit the program

What is Project-Ymer YMT files.

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.
