Title: Software to change CPU speed on MEGA STE?
Post by: complicated on 30-04-2023, 18:23:08
Does anyone know of any simple, light on resources software to change CPU speed on Atari Mega STE?

ATM i am using Xcontrol which can change speed to 8mhz/16mhz/16mhz cache and it works great. However it`s not light on resources and can sometimes mess up other things, like running HD adaptions and other software/games. I really don`t have any use for Xcontrol except for the CPU speed change so would be nice if there is some other software out there which do the same but takes alot less computer power or computer memory.

Thank you. Can this program change back to 8mhz or does it just set speed to 16mhz cache?

Here is one what sets to 16 MHz, or prints that it is already at it, and other what sets to 8 MHz :
16MHZ.TOS (https://atari.8bitchip.info/TOS/16MHZ.TOS)
8MHZ.TOS (https://atari.8bitchip.info/TOS/8MHZ.TOS)

Works great, thanks! Now i can finally throw that terrible Xcontrol in the waste basket :)
