Re: PMDoom music?

Yeah but wasn't the music specially preprocessed and/or tweaked for his player? I mean it's not a universal player where you just incbin your favourite mid file and play it, is it. I think the player eats fairly straightforward MIDI-data, and that some early version of the MIDI player required just...

Re: Atari TT030 and system V

When I last tried Debian under TT emulation, I noticed that Linux and all the somewhat bloated libs & base system background processes take quite a lot of memory. Just starting the system with Bash shell takes almost all of the 14MB of ST-RAM. So, you're definitely going to need FastRAM to do an...

Re: PMDoom music?

Doug's music code in BadMood is pretty nice. There's support both for playing the music through MIDI, and Doug's CPU-side soft synthesizer that AFAIK takes only few percent of CPU.

Re: TT030 clone - is it possible ?

I would think Falcon as a base is a better idea as well, simply because of the updated TOS, ability of custom video modes, DSP, etc. If the bus and CPU speed of the original Falcon hadn't been handicapped, it would have made an awesome workstation system. If the software didn't utilize the DSP, the...

My normal interaction with the debugger is scripted, so I don't need to remember anything unless I do something new. Normally I just need to pick a suitable debugger script from my "collection" and maybe do a little change (e.g. to catch a different OS call). Btw. If the builtin help outpu...

Re: Need idea to do something faster

At least on Hatari (and using a C compiler), that said algorithm is roughly 6 times faster than a plain div/mod (don't know how it does on real hw). For ST/STE emulation, Hatari should be cycle accurate, especially for things that use just CPU. And you can use debugger/profiler to measure the perfo...

Re: Is it possible to run System V on Hatari?

Hmm, I was running the latest EmuTOS (0.9.9.1) and it didn't give the option for TT High (maybe I needed to play with the video settings.). I didn't have a chance yet to try it with TOS 3.06. Did you use monochrome monitor ("-m" option in Hatari)? TT-high is monochrome only, and it's only...

One of them main difference between v2.0 and v2.1 is cache emulation with MMU. 2.0 didn't emulate cache when MMU was enabled. To get...

Re: blit buffer to display, vro_cpyfm or vrt_cpyfm?

I suggest you pre-scale the fonts and scale graphics output while rendering. This will be much, much faster (and better looking) than scaling the finished bitmap. For monochrome mode, best looking output would probably come just by scaling height by 1/2 i.e. dropping every other row. I don't know h...

Re: Anyone to convert a Z80 music player?

I just managed to do some measurements using gwEm's CPU measurer (is that even a word? anyway). Hatari profiler can measure an exact amount of cycles for you, for any part of your code. Probably easiest way to do that is adding symbol for start and end of the part of code you want to measure before...

Re: blit buffer to display, vro_cpyfm or vrt_cpyfm?

No, unfortunately not. That would only work if VDI would also scale the source bitmap up/down while blitting, but it does not (NVDI can do that if you add 0x8000 to the writing mode, but other VDIs cannot handle that; also it might look rather ugly). Might look ugly? Monochrome scaling looks horrib...
