Did someone say they wanted this running? Has to be the most unplayable game ever! And I've been playing Dragons Lair quite a lot. It's strangely compulsive...

Teaser time! Some pics of games running on the Jaguar GameDrive CD drive simulator. Most games are now running pretty solidly -- getting pretty close to a test build and then public release.

More Jaguar GameDrive CD work today. It's *nearly* running Dragons Lair now. The data throughput isn't quite high enough to stop the video skipping, not sure if I can get around this yet!

More fun with CD emulation on the JagGD today. More games now *beginning* to boot. Still plenty of issues to iron out, but things are progressing. CD audio still being weird, even though it's sortof working....

I've done some handy things on the JagGD in the last few days. I now have a virtual com port which spews out debug logs from the cart in real-time. Bloody awesome! And I now have Blue Lightening running on CD as well, although not entirely stable and without CD audio!

A pretty thorough overview of Jag GameDrive! Glad you're enjoying it.

Merry Christmas folks! It's time to kick back and make things which don't involve a soldering iron for a change.

NeoGeo cartridge PCM chip repro tested and working !
Uses a pretty @oshpark flex PCB and a rather large CPLD so it won't be the cheapest repro around, but it'll save games with crackling or missing audio.
Will get a few stocked up for sale on Tindie later on this month.

Biopede high-score competition!

Finally, after 7 months of intensive work, I can finally present my latest reverse project: the DL-0921 aka CPS-B-21

This is the brain of the C-board on CPS1 and is found on the A-board on CPS2.

You can find all the schematics and documentation here

Many thanks for @rickr000 for lending me his Lynx to fix this issue! It's only applicable to early Lynx 2 machines, and you'll know if you're affected. The menu will just be a black screen.

This is an interesting hardware incompatibility with LCD mods and old Lynx 2's.

A new firmware update is available for the Lynx GD. Boot your Lynx, hit OPT1 and visit the link to update your cart!

== Firmware 1.04 ==
Fix for the menu not displaying at all (black screen) on old revision Lynx 2 PCB's. The BIOS does not initialise MIKEY properly.

Got a Neo Geo Pocket with nothing new to play on it? Why not try the NeoPocket GameDrive from @TheRetroHQ?

How you can turn a load of pretty colours into functional hardware is tantamount to witchcraft! It's a good thing we're not in the 17th century...

Amazing stuff.

The Lynx GameDrive is back in stock in the UK at @RetroGamerStuff and @retrotowers. You can also pick up a NeoPocket GameDrive while you are there as well.

And before anyone asks, yes, the Jaguar GameDrive will be following in a few weeks.

Stoked to upgrade the Jaguar kiosk with a Jag GD from @TheRetroHQ! Time to load it up with games.

Awesome work!

This handy device turns un-programmed Jaguar GameDrive boards into fully tested, working and registered devices at the press of a large red button.

Useful, huh?

I'm off to press the big red button repeatedly....

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.
