Wow, cool

Any chance of a tut in the future?

well, didnt you base it on the japanese document?

sorry, yes I did, but obviously I couldnt read japanese, so I had to get in there and check it all before hacking away. I will say that the actual mod is not long winded. Its jsut really precise and delicate. Thats the only big issue.

I will do a TUT in the future.

Very sweet, I'd like to overclock one of those puppies...but man, I've been unsucessful installing 3 mod chips, so I think I'll let it be.

Wish you luck with the end of the auction.

how did you force it at 60-PAL?
Is it undoable?

cheers

qatmix · Post by **qatmix** » Tue Nov 09, 2004 4:34 am

nope, its a bridge solder point

dj898 · Post by **dj898** » Tue Nov 09, 2004 6:00 am

then wouldn't it be possible to desolder?
also if mod chip is fitted will this forced 60-PAL affect the output???

Couldn't you just solder it. The Master System had a bridge solder point, you had to cut it, then wire a switch to it and the other combos

why even bother

how did whoever figured this out figure out the various settings the pll-ic could do?

how did you keep the thing not over heat?
After half an hour playing of TER2 the thing gets hot

really? Thats strange. Did you change the powerpack? I placed a small drop of cpu coolant onto the chips when I did it. I tested shenmue 2 for quite a few hours and I had no ill affects.

Also I never ran it on a carpet. It was always on a wooden shelf with no obstructions near the fan.

I know this sounds odd, but obvously its going to be warmer where you are and the ambient temperature might be causing an effect.

TER2 might also work the DC harder than shenmue2

A good idea might be to get one of those extra fans of liksang, they are well cheap and that will help (I was pondering getting one but after my test it seemed ok).

glad it got there in one piece.

yea I swapped the PSU with PAL 240VAC one and no it's sitting on the metal shelf with about 15mm gap between its bottom and the shelf - I put the leg extender at four cornors. I do have lik-sang fan although lost the AC adaptor thing years ago...
maybe I need to run wire inside to tap the DC power from PSU?

By the way if I take the metal shield inside apart do I risk wires might coming loose or something? I've been thinking of the same cooling pipe setup the Japanese guy has done... or put the cooling fax at the side if the case but that will look like s*it...

also although using CD-X on VGA works fine I might add the mod chip down the tarck as I'm not a big fan of swapping disc...

I must say pretty impressive stuff...
how long did it take you to complete this one?

cheers

Removing the metal shield is a delicate operation. The wire is connected to a very small pin, even though the Connection is good, I would stray away from jolting it

If you want to chip it, just be really carefull when removing the board, and replacing it.

My mate has a liksang fan for his std DC, the powerpack is 12V 100mA

The jap guy had an old DC which had the pipes in it. You cant fit pipres to a new DC as it requires a totally different motherboard (I have an old pipes machine). Also the metal casing is a differnt shape.

Definately go for the external fan, that should do it.

Glad it works with VGA, Ive got a VGA box on its way (got one for ?2.99). It took me a month to get it all up and running (Sourcign the parts was a real pain). However Im really glad its gone to an enthusiast who will use it (i would eb interested in knowing games which you have tried).

When I get the time and money I might have another go (with the VGA overclock) but my mate is away for months and I really dont have the time.

dj898 · Post by **dj898** » Sat Nov 20, 2004 5:59 pm

probabaly I will get AC pack from Radio Shack to power up lik-sang fan

Games I've tried w/ VGA box so far...

Tokyo Extreme Racer 2 JPN
Space Griffon JPN
Daytona USA 2001 PAL white label
Quake Arena PAL white label

and many more - about 120 titles from my library - to be followed...

Try Crazy Taxi! I'm sure you know of the mad slowdown that occurs in certain places (just past the harbour, for one, in that park w/ the ramp and the cafeteria across the street). I'm interested if that's gone now.

dj898 · Post by **dj898** » Sat Nov 20, 2004 8:14 pm

Crazy Taxi huh?
I think I have that one some where... haven't played ages as it wasn't my favourite back then...

hmm just played Crazy Taxi 2 JPN and didn't see any slow down at all... in fact the game is dame too fast...
