Re: Emulator roms and cloading speed

Ahh OK, I see. If you did want to just use the Euphoric rom set, you can just copy the ".pch" and ".sym" files from Oricutron into the shared rom directory, and rename them where necessary to match up with the Euphoric rom naming conventions (although weirdly, I think I got the original ROMs and fil...

Re: Emulator roms and cloading speed

Another thing: MICRODIS.ROM doesn't have any tape loading code in it. The normal ROM is still used. If tape loading is slow, I suspect something has copied the ROM into overlay RAM, and Oricutron would therefore not do the turbotape patch (and nor should it; it would have to compare the ram every in...

Re: Emulator roms and cloading speed

Oricutron has turbotape patches for known ROMs. If some ROMs load tapes slowly, it is because Oricutron doesn't know how to patch that ROM. If it doesn't know how to patch it, it falls back to emulating a real tape (and hence loads at tape speeds, but you can use warp speed to counter that to a degr...

Re: Visual keyboard for Oricutron

I'd like to hold off on an official release for now. There's a couple more things I want to do for 1.2. Feel free to post a work in progress build.

Re: Oricutron 1.0 (EDIT: Now 1.1)

You can, but its not perfect. You have no way to know that the software running on the oric saw all your keypresses. the paste support currently implemented piggy backs onto code I wrote specifically to type CLOAD"" after autoinserting a tape. For this purpose, hijacking the rom routine is fine (and...

Re: Oricutron 1.0 (EDIT: Now 1.1)

I haven't implemented copy/paste on any platform. It was done by mmu_man for beos and other people implemented it for other platforms, so I don't know why only paste was implemented on windows. paste only works when software is reading the keyboard via the built-in rom function. There isn't really a...

Re: Visual keyboard for Oricutron

The change I committed also fixed a weird crash. You were reading off the end of the modkey array. I have no idea why that caused a crash, but on Ubuntu, with optimisation turned on, this generated a weird crash with an illegible stack backtrace in gdb. Turning off optimisation made the problem go a...

For no real reason, I have created a Facebook page for Oricutron.

All likes gratefully received :-).

Re: Visual keyboard for Oricutron

I've commited a fix for problems that showed up on my linux laptop. I haven't had time to test it on my Windows laptop or Amiga, but I suspect it might be fixed.

Re: Cumulus Issues

Thats correct, but with one caveat, high rated power supplies can have problems maintaining the advertised voltage if they are under-loaded, but I don't think it really applies here :-)

Re: Stuttering Atmos

Clearly the 6502 is executing the ROM correctly (and also must be reading/writing RAM correctly), and the ULA is reading the char ram correctly, but is reading the screen ram with bit 0 stuck at 0.

So it looks very much like a busted ULA.
