noromamaiRemoved all caps except the RGBS ones, because I want to test before I do the RGB bypass mod and for that mod those caps need to be removed altogether. Cleaned up flux residue as well. #snk #neogeo #retrorevival #retromodding
Put new caps in (except the 2200uF low profile one). Cleaned up, test... and still working... phew :). Maybe continue tonight with the RGB bypass. #snk #neogeo #retrorevival #retromodding
Keep forgetting how fragile the AES boards are. Bodged a few pads. My way of removing the caps is also to blame. I heat up one side, bend, heat up other s8de, bend, until it comes out. Works well if the pads don't come off... #snk #neogeo #retrorevival #retromodding
RGB bypass done. Feels like a little sharper and brighter. Currently still using composite as sync, no changes there yet. That's up next. #neogeo #retromodding #retrorevival
Pure CSYNC mod enabled. Can't really see the difference with using composite as sync, but I am sure someone with better eye can. #neogeo #retrorevival #retromodding
The stereo mod. Will run cable over top (again), not enough clearance bottom side for the 24AWG 2-core cable I am using. And all the sharp points sticking out could prick through the cable and make contact with the GND shielding of the cable. #neogeo #retromodding #retrorevival
These are the points you can use to tap audio from. Left, Right and Ground. The side I am using this time is line level audio, if you connect to the points on the other side you can control the volume of the audio with the volume slider just like a headphone. #neogeo #retromodding #retrorevival
There is very little space between the front side of the PCB and the bottom shell. So I will be removing a little bit (see marking) with a dremel, just enough for the wires to pass without getting squeezed between the PCB and the bottom case. #neogeo #retromodding
Dremel was not in my room, too lazy to go to the garage, so I used the smaller Mechanic (from #aliexpress) dremel, which worked much better actually for such a small area. Enough clearance for the wires now, so we can continue. #neogeo #retromodding
Soldered the wires to the audio and ground points. I didn't have black shrink tube, only white in that size and I could not have 2 white wires of course, so I used a marker to make it black (GND wire). Why not use that beautiful hole at the exact right spot? Screw hole... #neogeo #retromodding
Finished running the stereo audio cable to the back. Used gecko tape to keep it in place. Anyone know the secret to removing the plastic film from gecko tape, that shit is hard to get off. #neogeo #retromodding
I should be making a hole now for the 3.5mm connector, but the wife has already gone to bed. So instead I am beeping the connector to find out which pin should be connected to what and posting it here so I can look it up next time... #neogeo #retromodding
I am being banished from the living room by my wife. At night, every time I drop something (small) on the floor, it wakes her up (yes, even with ear plugs in). Quickly moved some stuck projects into corners. And... I found the dremel! It was in the room, not garage. #retromodding #needsintervention
Decided on the location for the 3.5mm connector and quickly made the hole before my wife goes to bed. Now I can continue making a bit more space on the table... Photo of the dremel (also #aliexpress) and the 2 bits I used to make the hole. #neogeo #retromodding
Connected the audio cable directly to the plug to test first. Everything still works. We have stereo sound. At first I heard a buzz in the audio, but once I connected the scart cable directly to the tv it disappeared. Cheap ass scart splitter. #neogeo #retromodding
Hmm... sound works (no surprise there), but no video. I thought I'd do it more simply this time, but no luck. CXA1145P pin 20 composite video out, 75 Ohm resistor, then a 220uF cap. That's what the docs say... More testing I guess... #neogeo #retromodding
Games That I Missed@noromamai Ooh, I have not seen one of those before. I love my 25-year old Dremel, but that looks convenient to keep in a tool bag.
@GamesMissed Yeah, I ordered a tool from Mechanic brand from AliExpress and quite liked the quality, so I then looked for other Mechanic branded stuff that was affordable and ordered some of them :)
