Sonic1 Tas playback hack
A while back I made a hack of sonic1 to playback tool assisted speedrun files, nobody has probably ever seen this so I decided to post it here. This hack features a built-in camera hack with scrolling speed increased to 64 ppf. I also made a super fast sonic hack based on the same codebase which use...

There is 233Kb of samples in that vgm file. Not all the length of the samples are used so reductions could be made with the correct software. This file uses v1.61 dac streaming so I do not know whether there is any software available to optimize this yet. The sample rate is 44100 so you could reduce...
You can get full access to ports under win 2K/XP using the UserPort driver. It modifies the port access table so that specified port ranges can be written to. I have used this to allow an OPL2 tracker to access my sound blaster 16 from win2k. Any type of program will have full access to those ports ...

The clr.w thing was the problem, I managed to replecate the bug by putting $100000 into d1. I was clearing d1 by clr.w, should have been clr.l.

Later today I will release a fix to the memory lear problem I could enable ym2612 duplicate write removal by defau...

And yes I still missed that bug, its probably to do with the mess my older projects are in. I have only recently started keeping any kind of order with my development. On a side note, did you try compressing vgm files with ym2612 write removal enabled, this mode can reduce some vgm files to 10% of i...
