Hi, and here are some real-hardware-test-results... I used the original Multicart and one of my Everycarts (based on the CSL PCB) The Multicart uses the "swapped" ROMs, the Everycart uses "flat" addresses... And the results were as expected: First the Multicart with the fitting "memcromb.bin": 20230...

very nice! can´t wait to see it :0)

Hi, here is the cartridge-memory-map @MADrigal is reffering to two posts before...

or have I got my Rom1 and Rom2 lines swapped around?

Hi,

/ROM2 for A13 is correct (at least for the "swapped" ROMs)
but you wrote you use /ROM1 OR /ROM2 as /CS or /OE => correct should be /ROM1 AND /ROM2

This might work?

Hi, it looks plausible...

PS: if this should be external the diodes need to be schottky diodes (with a low voltage-drop)... like in Chesh´s keypad-replacement

Yes, it works! only strange thing is: in Astro Pinball the left and right firebuttons are switched... very strange...

I finally got an original Joystick for the Laser 2001, to use on my Salora ;0)

It will need some Retrobrighting (i will do some lightbrighting as soon as the sun comes out :0))

Hi raritynine, very cool video! Cheers, TOM:0)

Hi raritynine! Welcome!
7 Creativisions - wow! But 3 are a good amount also :0)
You will find a few solutions regarding PSU and Controllers in this forum... But you sound like a "pro"
PS: once i also owned a Coleco ADAM (at least he Colecovision to "ADAM" Expansion :0))

Hi, yes, the adaptor creates the correct diagonal codes and should work with all carts correctly. Yes, all games can be started with "6" or "B" (i have not tried "T" or "G" on all games) Some Games start with any key from the LEFT Pad, some (like Astro pinball) even start with any key on LEFT or RIG...
