    Default Mega Drive 1 switchless issue

    Howsit?

    Been a while since I have been here. Haven't modded any consoles for a few years as life been heaps busy.

    Anyway I have modded my first switchless Megadrive after having the PIC (based on d3000 not SEBs program I think I got them from someone).

    It changes colour of the LED and changes region fine, but if you change it and press reset, the language stays as previous. For example if you were on PAL and change to Japanese press reset you get USA instead. If you are on Japan and go to PAL, you get 50hz + JPN.

    Switching the console off/on works ok.

    I did have to use a NOR gate for the led as the one I had are common anode. Not sure if that would cause issues.

    Cheers

    Sussed this out, it is how it works on some games (Sonic 2 and Ghouls and Ghosts). You need to power on/off.

    Streets of Rage, Quackshot and a few others I have all act fine using the reset button.

    Hi omp! You're absence was duly noted! Welcome back! The switchless mod sounds neat! If time avails itself, make like ooXxXoo and post a video of the mod in action!
