A lower voltage output for computer type monitors that use .75 to 1volt pp and then the option of a higher output for REAL arcade monitors that use 2-3volt pp. because the computer type outputs (the lower voltage) make the picture very dark on real arcade monitors. This would be especially helpful if you can use your pcb on playchoice 10 in an arcade environment.
The output is home level rgb it's just a ba7236af encoder with built in amp. For arcade level rgb you'd need to run the output through another amp (ultimarc etc) to get it to arcade levels.

My early one came with a regulator. I wired it up, it made the output darker looking so I switched back to using the built in 7805. Mine runs fine with just the built in 7805 using the kit + flashcarts. An easy solution is to buy a power brick that outputs over 1 amp.

Just remove the 220 uf caps from the snes rgb cable and you're good to go.

Pallette is the same as the default composite ppu output:

Only issue with my first run batch is the lack of grayscale mode which is getting added.

It fits just the top half of the case won't close because the pcb sticks out too far to the one side. I sent measurements to get an adapter made that should allow it to fit in both the nes 2 and av famicom, the one adapter should make it fit in both of these systems.
lettuce wrote:viletim, is the front loader nes hard to mod than the top loader nes? Also will you be doing a youtube video of the install?
Also is it ok to use a Hot Air Rework Station on the PPU rather than wick and sucker method....never 100% sure on Hot Air Rework Stations on retro gaming equipment?
I hot air out the ppu chip and then use a radioshack desoldering iron to suck out the solder left in the through holes before installing a socket. Zero damage to the pcb this way and no difficulty with the process.
This is why it needs an adapter.
