Holy moly, @TheRetroHQ Jaguar GameDrive flashcart is a wonderful piece of kit!

Made a handy shell for the mwp-606 adding EIC connector and switch!

Well, I wasn't expecting this. Twin Cobra starting to boot without the bad sound sram in there! Replacement ordered...

Tracing through the video generation circuitry, there's something happening. There seems to be some kind of video enable signal which is disabled and floating high, forcing low gets some crap on the screen with good sync, so *some* of it is working.

Ok, so it's Twin Cobra. Now that's worth saving...

Given it a clean up, one of the legs of the EPROMs snapped off while pulling it due to corrosion. New leg from the dead Final Fight SRAM transplanted.

68000 and Z80 running, but no video or audio.

What's next in the arcade PCB lucky dip?! This one has some water damage, needs a good clean before powering up...

TAITO original at least! TP011

Another arcade board fixed! And Final Fight, too...

Apparently you can get away with a 70ns SRAM in place of the 35ns used for the linebuffer.

Need to give it a proper test, may get some glitches and need to replace with a faster SRAM, but looks solid to me!

I never knew I even had final fight! May be a bootleg? Graphic corruption on sprites...

Woot! Running fully -- no audio was as simple as the volume pot being oxidised. Quick twiddle and we're good!

I felt like @GadgetUK164 with my systematic sleuthing. I might actually have to video some repairs, I find watching Gadget's repair videos bizarrely relaxing.

Now that is remarkably cool. And I do like lego.... and it would look great on display.... argh! I bet it's going to be expensive.

The ZX81 was obviously waaay ahead of its time! Wipe that baby down with isopropyl alcohol and you’re virus and bacteria woes are no more.

Top tip!

Very fair overview! The NGP system is tied to flash memory very tightly, which is why I use it, but the flash itself is slow to write to, hence the slow write times. And yes, that’s why it has as large a flash memory as I could fit in the device!

If anyone is after a NeoPocket GameDrive cartridge, they are in stock at both @StoneAgeGamer and @DragonBoxShop right now!

Just updated my NeoPocket GD case to the new style case.
Very easy to do, and its a well worth upgrade. It feels better, looks more like a real cart, and its easier to remove.
Thanks @TheRetroHQ!
