Re: Acorn Electron emulator with SWRAM?

I haven't looked into the ABR and AQR cartridges (mainly because I didn't know about them). Any quick pointer on how to use them in MAME? Start MAME with a ROMBOX+ and AQR cartridge installed: mame64 electron -exp romboxp -cart1 aqr You'll then have 16K SWR mirrored in banks 0/1. Ideally you should...

Re: Acorn Electron emulator with SWRAM?

I have several options for using SWRAM on my real Electron but I am looking for an Elk emulator that emulates SWRAM. Which real Electron options do you use?

I have several options for using SWRAM on my real Electron but I am looking for an Elk emulator that emulates SWRAM. Emulating ROMs is no problem in MAME, Elkulator or Electrem but how about emulating SWRAM? I was really expecting MAME to be able to do this but can't find the option. Btw, I am looki...

I have no way to test this. But here's my best guess. I added WAIT at 2 different places I found a better way of limiting the speed, without using WAIT or INKEY, by modifying one of your SOUND statements! This also fixes another issue with running it on a non-Beeb (or Electron) platform, that your ...
