*LOL* Overclocking with 32 MHz clock reminds me of the experiments with my 500 in 1990 or so... My 15 kHz monitor was screaming but everything else was fine.

SuperBuster was designed to run @ 28Mhz. Some users have overclocked their motherboards past 33 Mhz. This mod only increases the clock to the Zorro2 logic in SuperBuster to 14 Mhz. Thats hardly overclocking!

** NEWS UPDATE **
There have been significant changes made to this thread since it was first posted!

please elaborate

All is explained on the EAB thread. Just follow the link in post #1.

This mod does not speedup Zorro2 DMA or alter Zorro2 device timing. It's a simple fix to enable SuperBuster to run Non-DMA cycles at full Zorro2 speed. (approx. 3.5 MB/sec). It will speed up buffered copymem cycles on the A2091 if you have Zorro2 fast memory installed and use Vbak2091 (Aminet) or Ralph Babel's Guru ROM.
