Haven't done a lot of retro computer activities lately, been busy working on several retro games consoles instead:
First, on my Atari 7800 - been playing a lot of Atari 7800 & 2600 games this past week with my recently aquired Atari 7800 2-button controller, including trying out some newer 2600 homebrew titles on the UnoCart.
I also received an RGB booster expansion on Thursday for the PC Engine and fitted it to my Core Grafx II console. The RGB quality is damn good, though as some reviews stated, the output does suffer from some slight picture interference/noise - if I can't solve it, I can certainly live with it!
Today I switched my attention to my newly aquired Sega Saturn Model 2, specifically the Aliexpress clone All-in-1/Pseudo Saturn Kai cartridge that I received a couple of days ago. The cartridge had issues running a couple of games that it should have otherwise been able to run. So I found the simple solution whilst searching online - open up the cartridge and stick tin foil onto the back of the cartridge shell. I was sceptical, but indeed it definitely did work and now runs everything it should. Just a lack of proper shielding in the cartridge causing issues. I've ordered some aluminium foil tape to do a more professional job, but the tin foil & electrical tape will suffice for now.
