SUPER clean and tidy SMS2 modwork (RGB bypass +jailbar reduction/mitigation)
Posted: Wed Sep 16, 2020 2:45 am
I came up with a really clean way to do RGB bypass on SMS2 consoles.
Here is a video that I made:
Here's a pic:
Mods:
* RGB
* THS7374 RGB bypass (voltages are correct)
* Jailbar mitigations (based on PDF. see below)
* the usual 60hz mod and master clock changed to 53.69mhz for nTSC timings
* DC coupling capacitors added to VDP 5v pins (by default there are none)
DIN is wired with same wiring as megadrive1 / sms1 din, but the composite video pin is attenuated composite sync (and TTL sync is also available, on the sync pin)
EDIT:
Oh, and I'm selling these pre-modded, and you can send me yours and I'll mod it. I do this professionally, for a living. Contact me @n4of7 on twitter
