#MEGA65: Part 3a (ZX Spectrum core)
86I tried loading a new core into my MEGA65 - a ZX Spectrum.
It works!
TL;DW (too long; didn't watch):
[1] Only works from the internal SD card slot (but you can flash the core from either)
[2] You can use your MEGA65-formatted SD card
[3] Uses VGA output only, and the 3.5mm audio output
[4] Expects EXSDOS 0.8.8 (won't work with 0.8.9)
[5] I used the R3/Devkit version of the core
[6] If you power off/on you usually get rubbish on the screen - wait a short period before powering back on
{As I'm using a Mac, it's creating its rubbish dot files on the SD card ... hence the rubbish entries on the C65 screen.}
Hold {NO SCROLL} when powering on to get the core selection menu. Select an empty slot and edit - choose the #ZXUNO core from the SD card (either SD card slot is okay). Once it's finished, press {RETURN} (or any key I guess).
You now have a #ZXSpectrum.
Pressing {ESC} will trigger the file selection menu, or you can use .tapein command ... but you need to have EXSDOS and the Speccy software loaded onto the internal SD card.
Some additional tips, including how to increase the clock speed, are here:
