Ive played it back in 97 I think,and this game still sadly hasnt received a patch for these two bugs that are really annoying:
1. When you send your thugs to beat enemy thugs without manually directing their path,and the enemy thugs' leader goes inside a house,game freezes
2.Some characters that are being transported and dropped from heli in cells stay in these cells forever(afaik when PS is blown when characters are there).

Also,its sad PSX version had better resolution,but other bugs(if I remember correctly,gangsters had two minigun icons instead of minigun and laser)

Any hope some smart dude will do an unofficial patch? =)
