Re: DosBox 68k port to Amiga/Atari

Just released my final update to this port to fix up the native MIDI support. This is now a pretty solid port and would probably be usable for some old EGA/VGA on an overclocked 060. Source code is available (SDL based port) for anyone who wants to port this over to Atari. https://youtu.be/tb-0EsIrbfw

Re: DosBox 68k port to Amiga/Atari

I tried this change and it does work. usescancodes=false The majority of the keys are mapped correctly on the Milan's PC keyboard. Not sure how old my version of DosBox, it works and I installed a ran an ancient version of Tetris. It runs but very, very slowly. Don't forget that you can also use CT...

Re: DosBox 68k port to Amiga/Atari

Old thread but I recently released my updated 68k port of DOSBox for Amiga AGA/RTG. It's still missing a JIT so it's bloody slow but just about usable for some old PC games and utilities on an FPGA or overclocked 060. I've included the hacked source code with the Aminet release in case anyone wants ...

Re: Quake 2 ported to Amiga AGA...

Quake 2 AGA v1.07 , if I had another 20Mhz then it would be really cool. This port is at the end of development now, I can't do anything else with it to make it faster. Can you somehow reduce its memory consumption using minimal gfx options etc so that it would run in 14MB of RAM? When I first port...

Re: Quake 2 ported to Amiga AGA...

Port it to Falcon and you will have additional 20MHz! :) + some SD-RAM... can you tell us some more technical things? e.g. what are biggest bottleneck? how much time you lose on C2P...? I'm no Atari coder, sorry :) Not really sure what the biggest bottle neck is because I don't have a profiler with...

Re: DosBox 68k port to Amiga/Atari

Hiya, I was hoping to get to a mid to high end 386SX speed with a overclocked 060 (eg 80Mhz). Without a soft core it's more like a slow 286 at the moment :lol: Yes ScummVM runs a lot better and is not as heavy because it's not actually trying to emulate the x86 CPU. I haven't managed to profile it, ...

DosBox 68k port to Amiga/Atari

Hiya, Not sure if this is the right place to post this. I've spent some time recently trying to port the popular DosBox program to Amiga AGA (060 only). The actually code has been relatively easy to port across and I already have it running on my A1200 . The problem is that it's going to be far too ...
