I think most people already know of the red Hu variant of Champions Forever Boxing, but does any one know if it had a different barcode than the black label? I stumbled upon the following in my search for the answer.

The common one:
TGX040077
092218001368

The unknown:
TGX040074
092218001337

The box seems identical to the common one outside of the barcode and serial. I do not own the box...

I have a SuperGrafx with the exact same damage. Kind of odd that the shell is in perfect condition with this much damage to the mobo. I wonder if its common on these systems... :-k

I bough mine from Dalder a few years back and was in the process of doing the same repair except I got distracted and its been sitting on my workbench. Not trying to Hijack the thread...

I will be following this with great interest!

Ive been playing through Ys book I and II the past week or so and have been having some horrible read issues with my Duo using a backup (because it won't read my orig grrr!). I was all ready and prepared to do the laser pot adjustments when suddenly my games just worked flawlessly with the unit disassembled. sooo...

My issue is with this pos thing right here!
IMG

When it is in place none of my originals boot... at all! On the other hand a damn backup will play 85% of the time, but with issues loading music / audio.

Pop this sucker off and my orig and backups play 100%... wth...

Wth would cause it to do this? Does this mean the laser is possibly scraping up against the tray cover? Can I even find a replacement for this thing?

Vids anyone?

Loading the Sapphire Bootie - cover on and off
Loading a backup of Ys - cover on and off

I have all of my classic consoles connected to my projector.

It sits right next to my bed, so its optimal length for that short ass controller cable.

And since my CDROM is dead, I currently use my xbox with mednafen_pce to play my CD games in glorious 720p

Well after attempting a region mod on my Core for the 15th time, something horrible happened... :cry:

One of the big 21 pin gray ribbon cables had snapped almost completely off the mainboard.  :oops:

After looking at it for a minute or two I couldn't think of any way to properly reattach the cable.

So I decided to rewire both of them... 2hrs later this is my result.

yummy wires

love this game!


and well it works as normal now... Yay?

I'm not sure I want to attempt the region mod again   :|

Ok so I took a crack at the region mod and well lemme tell you what... Grrrrrrr!

sooo...


IMG
IMG
I ordered the IC's, made the PCB and got it all wired in!(Ignore the yellow wire... it is to be soldered to switch b4 closing (ground on pin 29))

IMG
mod on!

IMG
mod off!

ok so now here is the issue...

After about 30 seconds the screen gets all scrambled, beeps and glitches all over the place. Power off and back on a few times and eventually it just displays a white screen.

I checked my wiring to the pins and on the PCB atleast 15 times so that isn't an issue.

After about an hour of going over this crap I figured I had ruined the IC's somehow by overheating or something.

So I build a new one from scratch being very careful with the amount of heat applied to the pins of the IC. I wire it up, and it plays longer, but eventually it does the same thing!! WTF!!!

Another hour or two goes by and I cannot pinpoint the issue... So I said F*** THIS! de-soldered everything and wired the original pins back together and now the unit is back to normal stock, but works...

So my question is this... what the hell is going on?

Has anyone seen this before?

Could it possibly be my cable length? I can't think of anything else... I'm stumped...

Fret not my good sir!

I'd bet money on it being the system card...

Soon enough you will be presented with the following screen of pure awesome!(assuming you buy another system 2 card)

Quote from: ooPo on 03/08/2009, 03:35 PMThat's a nice quality picture for a projector on a classic system. Which model is it?
Its a Sharp XG-C60X... a little old, but it handles 480i pretty well.


Ok now... I attempted a laser swap with a working Sony Discman D-33, but it is acting the same as before.

It spins the disc up and sounds like its reading, but after a few seconds stops and powers off.

So upon closer inspection I found this...

IMG
a broken cog :(

It seems to still spin pretty decently and I'm not really sure what effect this has on the lense sled. So... What to do now...


So does anybody know where I can get this tiny gear or another solution?

Also what should the POT on the laser be reading for the PCE/TG CD unit?

I was browsing ebay and found a listing for a defective PCE interface unit with the CDROM and a Core Grafx for $48 plus shipping. I thought to myself what the hell I'll give it a try.

Well it finally arrived yesterday afternoon and I began to troubleshoot the unit. Seperated the CDROM and PCE and powered them on individually.

First I test the CDROM unit. Ok it spins up, makes some nasty noises and stops spinning... So its a Laser issue maybe?

Now I attempt to power on the Core unit and get absolutly nothing, not even a flicker on the screen.

So I dissassemble the unit and this is what I find...

IMG
IMG
A nasty crack in the mainboard thats about 2" long and severs traces along the bottom and top of the board.(*note* Pictures are taken after I scraped the board to expose the traces)

So with some patience I follow the traces and attempt a repair.

IMG
**placeholder for top pic**
ok soldering done(green circles indicated areas where traces were severed)

IMG
now some hot glue to hold the wires in place

IMG
reassembled

IMG
testing... YAY!


So next i'm going to dissassemble the interface unit and CDROM to see whats going on.


Also, does anybody know where I can purchase a region mod preassembled PCB on the cheap?
