Re: N64 Gameshark Pro schematics

Yes, the ROMs that come with the Gameshark tools are encrypted. You can get them unecrypted here. Please moderators, if it's bad to link to these ROMs here, tell me and I'll remove the link. Unfortunately, My device is Pro Action Replay and not GS. I couldn't find the firmware, and after awhile I j...

Re: N64 Gameshark Pro schematics

I had an idea but couldn't try it, since I already have removed the flash ROMs and put sockets on them. The idea was to make an adapter with an PLCC32 socket on an end and a DIP plug (or whatever your programmer uses) in the other end. I once considered this, but unless i am mistaken GS hardware ha...

Re: N64 Gameshark Pro schematics

Buying GS is a mistake itself. I have couple of them, both bricked. I wish there was easy method to reprogram the firmware.

Re: Thoughts on this "unlock" of levels for Mario NES

Anyway to safely reproduce these glitches??
With a console, probably not. Standard NES controllers might cause a excessive power drain if plugged incorrectly.

Re: Thoughts on this "unlock" of levels for Mario NES

Something like this happened to me with goonies 2, first door warped me to the last door of game. At the time, i was messing around with controllerport, so unplugging and plugging a controller might have a similar effects.

Re: Charge Pump Lockout Defeating Methods - Are they Unsafe?

Voltage required to explode the core out the IC is suprisingly low. (I have done this few times accidentally!) I would stay away from piratecarts, or at least render the lockout defeat inactive. Negative voltages, or transients are a bad thing. I doubt that piratecart designers paid very little atte...

Re: Charge Pump Lockout Defeating Methods - Are they Unsafe?

Worst case i have seen was controldeck with defective regulator. After prolonged use, even the genuine gamecarts started to crash. Probably logic voltage (+5V) had risen up significantly, and not only damaged the controldeck, but the games too.
