Been meaning to post these pics and updates from Round 2 of my testing of the Jammaizer prototype, but better late than never... I have given the SNES/SFC, PC Engine, Mega Drive and Original Xbox (alongside the PS1, PS2 and Saturn) a solid run for their money on the Astro City with the Jammaizer. No issues found, the sounds are crisp and loud, the video quality is absolutely stunning and the controls work fine.
Krikzz's Everdrives were used on the SNES and Mega Drive, the Original Xbox is Softmodded and the Super System SD 3 was used on the PC Engine. All RGB cables used for testing are from Retro Gaming Cables except for the Original Xbox which where I used the Advanced Scart Cable from Microsoft.
I don't have RJ45 cables for the PC Engine or Original Xbox yet, so I used a Tototek (TTK) PSX to PCE adapter and a generic PSX to Original Xbox adapter which worked perfectly with the MC Cthulhu boards. I used a SNES/SFC to PCX adapter from TTK with no issues also (the "Select" button wasn't usable as it's mapped to Select on the PSX, however the final revision of the Jammaizer fixes this with the push buttons/header on the PCB). I had a set of SNES RJ45 cables once but they're assumed faulty as they fried the sound section on my SFC 1-Chip console, so was scared to plug them in! :/ -- I'll get around to getting cables soon, but in the meantime this setup works just fine for 1P playing solo.
The MC Cthulhu chip doesn't support Mega Drive controllers (neither does the Brook Retro Board), so I found that using a PSX to Mega Drive adapter (also from TTK) worked wonders and I'm now able to enjoy 6-Button Mega Drive games -- Streets of Rage 2 on a cab is a lot of fun!
The Button remapping feature will be really handy for the older consoles and I highly endorse it if you're going to be playing them in conjunction with these adapters or cables. Anyhows, enjoy the cab pr0n, and get your pre-orders in guys!
NOTE: I tested some DOA3 and other games on the Original Xbox, the JSRF photo is just to show quality of the video for whoever here had asked for it (it requires analog controls which aren't supported).
ALSO: I have tried my best at taking photos of the CRT/cabs with my iPhone 6 and there's an annoying hanging light always reflecting in the screen, sorry, trust me, it looks a hell of a lot better in person!
