Hey.. I can also use USRCHEAT.DAT to play HG/SS game with raqib12's patch that has trimmed the roms.
I think that trimming roms with raqib12's patch won't affect the ability of using USRCHEAT.DAT.
Hey Thanks Raqib12! I use DSTT and there is no freeze during gameplay. I could enter and exit anywhere without black screen when I played with HeartGold v3.5 for about 7 hours. No problem with my DSTT card.
