#General Sound firmware
This is an original firmware sources for well known sound card for ZX Spectrum.
##Bug fixes
Original firmware from 1997 was a little buggy. There are a few bugs was fixed
in 2007 (see firmware/gs105a.txt also) and in 2015 (see firmware/gs105b.txt also):
- Modules with more than 63 patterns;
- Wrong speed of the last played note;
- Wrong sample speed;
- Unnecessary first playing note report;
- New command added: #6A - Set player mode (skip module stop command);
- New command added: #6B - Turn on sample relooper;
- Stop playing looped sample if 9xx command has wrong offset;
- Redundant change sample sign operation;
- (opt.) Skip intensive RAM test on reset.
The fixes are made as binary patches, so all routines are still in their places.
##Test files
test_data directory contains a few modules which original ROM 1.04 cannot play
correctly. ROM 1.05b fixes this.
##Known issues
Samples with short loops (less than 1024 bytes) are still playing incorrectly. Use relooper to fix this.
