Re: Devpac 3 - Where to start?

Do you have any experience with C? Most things in C have a direct equivalent in assembly language. BASIC is also helpful to know to understand program flow, but it won't teach much about memory addresses.

Re: TT and monitor stand

I'm sure the TT was specifically designed to take a monitor. Almost every TT setup I've seen has a CRT sitting on top. Some of those old high quality CRTs weighed a ton, like 20-30kg or even more. I've put heavy CRTs on my Mega with no problems. A desktop computer which you couldn't put a CRT on wou...

Re: SMSPlus for the Atari falcon

Unless you rework each game like Anima did with the x68k and the Neo Geo games there is no way you can emulate it on a standard Falcon. Megadrive should be unlikely on a CT60 without supervidel either way. Genecyst the oldest emulator needed a pentium with 8MB of RAM to work so it is within the CT6...

Re: SMSPlus for the Atari falcon

Using the DSP is an even crazier idea ha It's probably a bit overkill. Mapping the SN76489 tone channels to the YM2149 should be really easy. You'd just need a lookup table of 1024 pitches to convert them. It looks like there are only 3 frequencies and 2 types of noise. You'd only need 6 lookup tab...

I don't understand why are you so concerned about EA calculation on 060. It will be a magnitude faster than your immediate EA + SMC code. Also, if it's called only 200 times per second, how simple move.l (a0)+,$ffff8800.w can be a speed bottleneck on 030? The code needs to run on an 8MHz 68000, so ...

Maybe VDI size should be restricted to <1024x768 when 4MB or more memory is used with TOS version <= 3? Unfortunately it also happens with some resolutions less than 1024x768. Here's some tests using a MegaSTE 4MB TOS 2.06 (no NVDI): 16 colours 768x720: CRASH (size mod 256 = 0) 832x720: CRASH (size...
