Which Spectrum core did you use ??? (And Arcade). The only core's I knew of have been made on Development boards, not Minimig 1.1

Me wanties, pllllllllllllllease !!!!!!!!

It was a while ago (and I am not at my computer) but I am pretty sure it was : ZX-Badaloc (who's website seems to have been deleted).

Just a couple of the ones from Mike J's FPGArcade.

They are not hard to port. The hard bit is creating a new PIC to load games.

As a side note, would it be possible to run Risc OS natively on the Arm 3 in a minimig?

???

MiniMig v1.1 PCB doesn't have an ARM, it has a 68000.

I know

What I meant was (if you look at the video) someone has released an Arm controller for the minimig... would it be possible to run Risc OS natively ?

my bad

D'oh! I see what you mean.

The ARM7TDMI controller is just a drop in replacement for the PIC to increase the code space and speed up execution allowing for more complex programs (e.g. hard drive emulation).

The PIC's purpose is to program the FPGA on power-on (and do some bootloading) and provides the interface between the FPGA and the SD card for disk emulation.

It cannot be used as a CPU within a design. So the answer is NO.

Or it may have been ZxGate
