Would be cool to offer a more native solution ! I have a few 2934 chassis myself aamof.

@geekmiki Ah yes this is very very first batch, before the V2 was released unfortunately.

@geekmiki i forgot if I sent you a pre modified unit or a stock V1. Usually I ask before shipping. @bagheera369 sure just lemme know which recal you have and I’ll mod it before shipping if necessary. Next batch will work on both properly!

OH! Good point. I traced it and it goes to the guncon port! So it should remain connected if you want to use that feature. With this small, extra bridge, and keeping those two resistors.

OK ! Confirmed, RecalBox video mod works identical on V2. Correction : For interlaced output I need to make a change to my circuit. I have 20 or so more for sale now. I will reach out to whoever PM'ed me and please write here or PM if interested !

@onekei I have a V2 at home that I will do shortly for @300wins and the analog video section looks identical. The GPIO outputs 6 bits of R, G, and B that go through a resistor ladder the exact same way V1 does I would assume. I will confirm early next week.

@DRAGONKZ oh I didn't know the CPS2 header could output the extra channel ! I have built a separate expansion for it on a new model (not pictured yet).

Also, @DorianGray made me realize that TD-IO V1.1 has a different potentiometer location. I have changed my design to accomodate V1.1 so I will ask people which version you have moving forward!

+1 Swell Chap.

Your new audio module on X-Men looks wonderful 8)

@danringer I was hoping to sell a few to recoup some money for the time I spent designing it. After that I might just upload it somewhere online for people to make their own. I've lowered to 20$.

Checking interested ! I designed a neat, custom case for the TD-IO. If anyone is interested, I can make some and ship them out for 20$ a pop, including machine screws. I have light gray, dark gray, red and black PLA filament. You can also choose with or without mounting legs, just lemme know...

OK! Installation pictures. STEP1: Look at PCB. Know which parts to remove. STEP2: Remove the video DAC circuitry. If you use hot air, I would wet all the solder joints with leaded solder first, pour some flux, and barricade the neighboring plastic parts with kapton tape or aluminum foil. Tack...

@Samurai_j I noticed two things using an oscilloscope. On the same game, real board vs recalbox, I measured the time it took for a pixel to go from black to white (slew rate). One pixel on a 15kHz screen is roughly 150 nanoseconds. On the recalbox it was about 38ns from the GPIO pins, as opposed...

I'm not 100% sure, but I think the video circuit is unchange from the original one, so technically should be OK. Someone else asked in a DM and will provide a picture, will confirm then.
