The following region locked N64 games don't have a fancy screen telling you that you can't play on your setup, they simply show a black screen.
These are some of the more problematic games, since they could be outputting NTSC50 which a lot of T.V.'s don't like.

Note: This allows you to play the PAL game on a NTSC console (JPN/USA). This worked on an emulator, didn't test on real hardware because the Master Code is way too long to input manually. (Will try to remember to test it later, by downloading the master code in a cheat file).

Here's a bonus code, if for some reason someone in the future would want to look into this area of the disassembely to try to see how buggy the game is without the required expansion pak installed:

==================================================

[Mezmorize]

I made a batch file to scan N64 ROMs for the 64 different hex strings that make up MTC0 master codes.
That narrowed down things a lot.

The batch file would leave me a results.txt list of just a few hex strings to look for.
From there I narrowed down the list even more to make sure the strings were properly aligned and not just random occurrences.

And finally, with the hex strings that were indeed properly aligned, I made some RAM dumps to confirm if the hex string from the ROM was also in the RAM dump.

After all that, here's the results. Just need to change the 81 code type to F1.

Surely a lot of these were already hacked many years ago, so I'll have to look at the database for each game to see what's new.

Nice work on the master codes!

International Superstar Soccer 2000 (Europe) (En,De)
Play PAL Game On NTSC Console
F0003295 0000
Just learned that sometimes F0/F1 codes are needed over 80/81 for region bypass codes.
There has already been many times where I could hack the code into the ROM and it would work, but would not work on real hardware with using a cheat device code.
Decided to try changing the code type and it worked, making it playable on real hardware.

Made another discovery, changing the code type from 80/81 to F0/F1 also solves the problems with (most of) the previous codes I hacked that made my TV lose sync.

After wondering why so many of the Master Codes I had found, didn't appear to be needed (since there were tons of codes hacked years ago for some of the games), I found out why. It seems like the majority of the new ones are useful to enable ASM cheats.
