For me, TotalChaosAGA works splendid on my Blizzard-IV 030!
It`s like it`s made for it ;-)
Ppl who find it a tad bit slow could try the following;
1. Open Prefs/Overscan, and set it to default.
2. Disable cpu-consuming commodities.
3. Use the dos-command Addbuffers on the partition.
(i.e "SYS.> addbuffers Games: 800")
The latter makes it start up faster.
