changing a SF CE into a HYPER FIGHTER

i know this is possible but how is it done

Thanks

I know that the Hyper SF2 mother board has a higher clock speed, than normal CPS-1 mother boards.

Remove roms 21 through 23 on the B board, replace them with Hyper Fighting chips. It was designed by Capcom to be a straight rom swap, so it's easy.

Not so easy. The game is also meant to run faster so the 10MHz CPU
needs to be replaced with a 12MHz one. And the CPU on CPS1 mobos is surface mounted (PLCC package), not the easiest thing to work with...

shit i thought it was just a easy rom swap

ok so if i had a hyper fighter mother board and put champ ed roms in that, would that work ?

I've noticed that sometimes Capcom used a 12MHz CPU (but running at 10MHz) even with games other than SF2HF. So if you have such a motherboard only the oscillator needs to be replaced and this is easy.
A CE romboard (or any other CPS1 game) on a Hyper Fighting mobo will result in the game running a bit faster.

ahh i see , ok i was gonna make 1 good game out of both see

i think ill just send my CE board to you when i get paid see if you can sort it

Thanks

I think I can fix at least the missing red problem: I received a final fight board that had the same issue and managed to locate the bad IC that was causing that.

Trevor spencer · Mar 14, 2005

ok thats cool ill PM you nearer the time im going to send it

Thanks

Nah, it is that easy. Capcom sold rom swap kits that were just the three rom replacements. I've got several of the kits NOS in my closet right now. There was no A board swapping necessary.

I was convinced that only the Turbo/Hyper fighting version had a 12MHz CPU but I've just checked the emus and the Champion Edition is also 12MHz so yes, you just need to replace the roms.

I thought all CPS1 games were 12MHz like CPS2.

I am not sure about this. Can anyone here confirm that the CPS1 system comes with different CPU speeds? Just because MAME (or other emulator) uses a different CPU speed to emulate some CPS1 games dosent confirm the CPU is indeed clocked at a different speed on real HW.

There are problems relating to speed and wait states that MAME (or any other emulator) dosent take into account yet. This is certinally the case with CPS2 games so it would go hand in hand that the same thing happens with CPS1 also... and many other systems including neogeo for that matter.
