Hey dudes!!! I recently bought a NES from a flea-market. It included some games and gamegenie with a loose SLROM board on it. So when I got home, I wanted to play the nes. Mario1+Duckhunt played fine, Track and Field 2 played fine, the Pirate Multicart that came with it played fine, so here I go...t...

I don't know?

How does the powerpak do that?
If the powerpak can do it, why not overrule the powerpak thing?

Is there any emulator that supports mapper 253?

Reason is, I have a rom that uses mapper 253, but I can't play it now, and I really want to.

so uhm.... nobody wants to try?

Hey!

Is it possible to emulate the powerpak?
I mean, the loader with someromson there?

What do you mean, change my forum handle? I just wanted to know if this was possible and if someone could do a conversion from fds to ines format. My FDS unit is getting worse every time I use it. And since I like this kid icarus, I was wondering if someone could convert this thing so I can try putt...

Mapper 42 maps the first rom page into 6000-7FFF by default, then maps the last 32k into 8000-FFFF. You can convert some FDS games to INES with a hex editor, and just by copying and pasting ...

so why is it that some early modchips of the ancient xbox (the big black one) had to be switched between 5v of the board?

And then again, the chip is grounded (via the GND pin).

I think this will work....but I could be wrong.

Hi! I was wondering if it was possible to fit both the PAL en NTSC CPU/PPU in a NES? The theory I had in mind was to cut or desolder the 5v pin from the board. Solder a wire from the board to the middle leg of a switch. a wire from the 5v pin of the PAL chip to one leg of the switch and from the oth...

Well....what pin would you connect where?

i'll go for the 3 pins option.
middle pin connected to gnd.
left pin to 5v on 1 rom.
right pin to 5 volt on rom 2.

I think I would use a physical switch.
I think that would be the easy way for me.
I don't know JACK about programming a menu (assembling isn't my strong pint ya know)
Physical switching is possible. I played around with it a little and in theory it should work.

no clue yet, but I just want to know if it was possible

thanx for the info man!

Hey peepz!
Is it possible to put multiple games of 1 mapper on a board? maybe by switching it.
If so, must I use seperate eproms for each game?

or is it possibe to create a menu or something?

nonono you didn't get it right.
I want to play 60pins casettes in my 72 pins nes.
So I need a 60pins connector and a 72 pins card edge
