Re: Doom?

The samples will be cheaper if you can fill the gap, but that might get more complicated. Do you know if there is a suitable IO pin on the PI? I think I asked a long time ago, but can't remember. If one hasn't been used for this before - but I guess it has on the 1MHz PI, is there one that can be us...

Re: Games on ROM

It think JGH wrote a program or process to convert to rom FS but only for a header that loads the actual program itself, due to rom being slower than tape I believe. Making the games ROMs the first time was a pain, but once you have a template, it barely changes. Making one of my games into a room w...

Re: Doom?

The speech chip has an eight bit data bus and some address pins and is connected to the slow data bus, so it is best programmed from software on the beeb's 6502, or possibly via the OS (I don't know the OS route). Putting analogue audio in via the PiCoPro is cheating even more than sending the sampl...

Re: Games on ROM

My games (not the "emulators" from disassembly ports) are all compressed with a ROM header that will decompress from ROM or an execution address that will decompress to the same place, so basically the games don't know that they are in ROM or RAM ;)

Re: Doom?

Rob, what do you think about using sample playback for your Doom? You could probably get away with 8khz at 4 bits/sample, but it might be cheaper to send the whole volume control byte. The tricky bit will be interleaving the sound updates with the screen updates and as a further optimisation interl...

There is a similar threads around somewhere. Most of my games can have the main exe' (usually the largest file) burnt as a ROM, but you might want to check by loading them into sideways ram first. If they are in socket 0 (master cartridge), they will Autoboot like a console. Astro Blaster can also h...

I meant sound input the the master's amp as an output from a cartridge - but worded very badly.
A bit like ElkPiTubeDirect, but I was only thinking of it looking like a rom or two from the master/elk side.

I don't know why, but I was wondering about plugging a pi into the cartridge slot of a master, or I guess an electron.

I don't know the turbo spi, but other turbo versions usually have a small buffer that allows slightly faster writes. MMC are already much faster than disc, so it doesn't matter that much. To confuse matters further, you might consider mmfs as it is still supported. The second MMC device will come in...
