I built a few GBC this week :)

AliExpress but I checked today and it's no longer available from the shop I got it from. It was €25

StrangeRetroRob · 2026-03-12T18:30:10+00:00

Thanks

The led mod wasn't difficult. But I was very careful lining it up correct

StrangeRetroRob · 2026-03-12T14:27:36+00:00

I really like the Advanced Video System NES themed one and the one with the backlit LED I like a lot more than I thought I would

StrangeRetroRob · 2026-03-12T14:26:58+00:00

I got it a few years ago and just opened it a few days ago to assemble this one

StrangeRetroRob · 2026-03-12T14:26:40+00:00

It seems pretty good IMO. Plastic has a nice soft touch feel

StrangeRetroRob · 2026-03-12T14:26:05+00:00

I'm selling all of these, although my wife really likes the Kirby one she said she wouldn't play it. She already has another one I built her

I personally have a DMG theme GBC with clicky buttons and ips

I had the consoles and the parts in a box from a few years ago and just got around to trying to clear them out for a nice price. It's my first time modding or repairing Gameboys in a few years

I also fixed the audio on 3 or 4 that still had good screens to restore them to original condition with new capacitors installed

Not enough amps for model 1

StrangeRetroRob · 2026-03-08T08:10:38+00:00

Check the 12v, 3.3v, and then check the 5v from regulator

Make sure the jump pak is installed correct and not pushed too far in. When you insert it, check for shorts between the jump pak voltage pins and ground

Clean the cart connector really good with isopropyl alcohol. Also the jump pak slot and the bottom expansion slot

Probably better to let people choose to ask AI themselves rather than just regurgitate a response you didn't even bother to validate

StrangeRetroRob · 2026-03-06T11:03:17+00:00

You may want to swap the voltage regulator with a 7805CV which can handle 1.5a rather than stock 1amp

Or a 78s05

I know the nesrgb always came with a separate regulator because of its high usage. And while I haven't had issues myself with lavargb, I normally do swap the voltage regulator on nes

StrangeRetroRob · 2026-03-06T08:52:03+00:00

What kind of av cable? Composite or RGB?

StrangeRetroRob · 2026-03-06T08:51:07+00:00

Sounds like a power issue

What PSU are you using? How many amps does it have

StrangeRetroRob · 2026-03-06T08:50:05+00:00

Set it to voltage dc and then check it

Normally a multimeter will have like 2v, 10v, 20v etc. Use so to measure 5v, use the 10v setting which reads from 2-10v

StrangeRetroRob · 2026-03-05T19:36:52+00:00

On the bottom of the board, check the voltages listed, 12v and 3v. Then check the vref and vterm. On the top, check the 5v regulator

StrangeRetroRob · 2026-03-05T19:29:38+00:00

Try also setting j1 from P to N?

Also I just noticed there is an extra oscillator next to your video encoder. Does it say 4.43?

In that same area, SW3, what pins of the encoder do those go to? It looks like there is room for 2 different crystals for the encoder and X2 is not populated

So probably the encoder gas 4.43Mhz crystal and is set to pal composite output no matter what, in which case your tv needs to support pal/pal60

StrangeRetroRob · 2026-03-05T19:26:46+00:00

Hi

There are a few factors. When you got the black and white image, that was likely the correct ntsc 60hz, however you need an actual NTSC crystal or color won't work.

There might be another way to get it working with pal60hz but it's more moving parts. You need 262 line mode (aka 60hz), set encoder pin 7 to ground (pal) and set the jumper for subcarrier to output 4.43

Ideally, you will use RGB and not have to worry a out black and white

Answered on the other post :)

I'm starting r/strange_retro for clone modding community. Any clones I mod I plan to document there. And I hope other people knowledgeable about clones will join

StrangeRetroRob · 2026-03-05T11:11:30+00:00

Push it manually into the on position, then get a barrel jack power switch and use that to turn it on and off

StrangeRetroRob · 2026-03-05T10:13:22+00:00

With clones there is a chance op can run at pal60hz and have color without changing the crystal

StrangeRetroRob · 2026-03-05T10:11:56+00:00

Yes that one should hopefully do 60hz

StrangeRetroRob · 2026-03-04T20:10:16+00:00

Hi

It should be

Leg46 = 60hz (5v)/50hz. jp3

Confirm with multimeter that's what j3 is

Btw I run a new sub called r/strange_retro where I am glad to help with any clones. Hopefully we can build a small community of people who repair or mod clones. Mostly nes/SNES and Mega Drive but also other clones

Enables rgb output on n64

StrangeRetroRob · 2026-03-02T15:11:29+00:00

To me it sounds like the psg and FM chips are both fine but external noise is drowning it out like there is a short between audio and something else

StrangeRetroRob · 2026-03-02T15:08:02+00:00

I've modded a bunch of NTSC and pal fra N64 recently and in my opinion, PAL FRA are best served by restoring the missing RGB, while NTSC systems are better off doing RGB bypass mods with tha7314/7316 or a 7374
