It looks awesome though (screen mod included.) I look forward to see what other awesome projects you have up your sleeve. :)

Edit:
I had a brain freeze and didn't think that this was probably an implementation of this thread: http://www.smspower.org/forums/viewtopic.php?t=10840

Wow, this looks very nice!

Can you provide the schematic and the logic for the CPLD?

I would very much like to build one of these myself, if it works well I intend to design a PCB layout so it will be easy for everyone to build their own if they wish.

Absolutely FANTASTIC!!

Someone finally did it!

I agree with Agent24, you must share the Schematic designs and the CPLD code with the world!!

Are you going to post this on a website?

Way to go man!!
I have to say it again.....just fantastic. :)

Regards,
Gerry O'Brien

Yep!
It was a previous Post he made. Showing how he replaced the LCD screen in a Game Gear.

I guess he was just saying that he used the same Game Gear unit for testing the Flash Cartridge.

Here is the LCD MOD posting he made:
