Radica plug and play

[19rsn007]

Hey people,

Don't know if this is the correct place to ask but I got hold of a radica plug and play console with street fighter 2 and ghouls and ghosts on there.

It's the only model that has 2 gamepads on there so 2 player games can be played.

I am considering to make a portable genesis with this, so adding a cartrdige slot.
Now I found the DevSter's Sega Radica "Know-It All Page" ( devster.monkeeh.com/sega/radica/) and the thread on the ben heck page but I was wondering something.

Hobbyists might be able to get a little bit of better sound by providing a second op-amp, and feeding one of the other sound channels to that op-amp.

I should post more info + pictures on how to perform this later

Does this mean pseudo stereo sound?

Does anyone have more info on this?

I'm going to make the portable with an old video doorbell screen which I saved.

I can probably make it work on a good powerbank using a buck booster for converting +5V to +12 volts (for the screen, since it only uses 80mA) and provide the cartridge slot with the +5 Volts

As you can see I have a lot of idea's but am working out some stuff

Anyone care to help me out with the questions I still have?
