Re: Modified TOS to remove resolutions limitation

the Desktop works in User mode, in order to read/write OS variables or hardware registers you have to swith to SuperVisor mode. No, it doesn't. In TOS, it is in Supervisor-mode all the time. You're right. I've just checked under emulator and actually the Destkop 1.62 works in SuperVisor mode. I was...

Re: Modified TOS to remove resolutions limitation

Since TOS does all the work anyway when it detects the mono pin, might you recode that routine so instead of TOS checking the mono pin, it checks the selection in the desktop menu ? nice and simple idea I tried it, but I always see a bus error (2 bombs) and an infinite reset loop if I set it up tha...

Re: Modified TOS to remove resolutions limitation

I've patched TOS 1.4 UK to allow selecting any resolution from the Desktop Preferences. This is probably only useful with the HDMI mod at this stage, since a monitor cable can only either be connected to the RGB lines or the mono-out pin at a time. This screencast shows it running under Hatari, but...

Re: Slow STFM blitter oddness

I would say the TOS in STfm has slower blitting functions than in STe. Bear in in mind STfm TOS has less space than STe's one - 192k vs 256k. Atari did some optimisation in order to fit the TOS in 192k (like using LineF functions), which are not present in STe TOS. It could have an impact onto perfo...
