I'll do what I like! :twisted:

Look at that dummy who can solder better in thirty seconds than I can solder in an hour! :lol:

Seriously, neat work! :D

Not bad for 30 seconds. Good soldering is an underappreciated art.

Neat thread and cool projects!
I made a S-Video to Luma & Chroma pigtail to get a clean luma signal from S-Video.
Image
I use it to play games on my monochrome green monitor without the chroma signal making the image grainy. The result is indistinguishable from hooking up only the Green (Y) plug from a Component cable. It works on any screen that accepts Composite, but true B&W tubes definitely look crisper.
GBI-LL by Extrems through S-Video, Luma signal only.

I wish my monitor was a bit bigger - The Gameboy image is only 6" diagonally.

Awesome! That really replicates an OG Gameboy screen!

I know that older monitors use to have RCA jacks for Luma and Chroma, but this reminded me of a high end cable I once saw. It was a 4-pin S-Video jack that breaks Luma and Chroma out to separate female RCA jacks. The idea is that you use one of these Y cables at each end, and a standard RCA cable in between to prevent crosstalk.

Help me understand this, Ziggy. Is this a cart with a big EEPROM that you flash once, or is this a cartridge with an SD card reader in the style of Krikzz? Can you flash multiple games at once? I’m fascinated, but I don’t have enough information to grasp your project.

What’s your goal?

The carts I posted are not flash carts like the Everdrives by Krikzz that load games from SD cards. They have an EEPROM that you flash once. Although I made them for myself for a very specific reason, they can be used in a few different ways.

Asked to fix an original XBOX that went RROD a year ago. Hard drive bit the dust, so no hot-swap to clone the encryption key.
Had to build an EEPROM reader cable to extract the contents of the chip directly. Being a 1.6 revision board I'll have only a few seconds to grab it on an XP laptop before the system detects intrusion and emergency aborts the power.

It was fun to build.

Nice! I have my HDD key backed up multiple places.

I put a new IDE drive in around 2016... but you never know. With JRocky's new tools you can null the key to all 000s.

How'd it end up?
