Following the trend on conversions, there is one that I'm really keen on seen happening.

For some reason it's pretty easy to get Super System 22 PCBs which is a superior or upgraded version of the System 22, but It' very complicated to get System 22 systems.

Has anyone seen or tried such a conversions?

They are even in the same driver in MAME!

If I got it correctly you'd like to run System 22 games on Super System 22 hardware, correct?

It seems a lot of work:

MAME said:
* "Super" System22
* - different memory map
* - different CPU controller register layout
* - sound CPU uses external ROM (i.e. pr1data.8k) instead of internal BIOS (C74)
* - additional 2d sprite layer
* - Point RAM starts at 0xf80000 rather than 0xf00000
* - "PDP" device, for automated block memory transfers (dsp ram, point ram)
 
I didnt expect so much work tbh.

Well I guess that will have to wait some more time, unless some clever folks with lots of free time decide to give it a go.
