Link to compatability list with utilities and patches:https://evilgames.eu/emulation.htm#snes-ntsc-patchesUPDATE: 13 April 2018
Updated the collection to feature one patch per game version. This way the compatibility table is no longer needed, thus making it easier to patch whatever ROM. Batch script for patching whole ROM collections fast has been included. Changed the above link to point directly to the updated version of the website as well.UPDATE: 02 April 2017
With the help of rainponcho any
PAL ROM can now be converted to 60Hz. Nasty region lockouts are no more! Further, rainponcho did also fix the music timing issues in both ActRaiser and ActRaiser 2. The downloadable archive on my website has been updated, containing all the new stuff. The NTSC patches for ActRaiser and ActRaiser 2 on RHDN are also being updated any minute.Why did you do that?
Due to users asking for specific game patches and how to create them yourself, I decided to create a compatability list, which helps you to convert your ROM into NTSC. The linked page includes a download option, which contains patches for converting almost any PAL game into NTSC, utilites for and information on how to create them yourself (do not spam them on RHDN!). The master list should cover all PAL ROMs.Patches?
For games that lock you out from playing in 60 FPS, I included specific patches, that remove the region lock and change the region of the ROM to USA (=NTSC=60FPS). For games that do not trigger a region lock, use either "LoROM to NTSC" or "HiROM to NTSC". To find out what type of ROM a game is, check the compatability list. NOTE: The patches are for headerless
ROMs only. I used No-Intro for creating the patches, but they should work on any ROM, even hacked ones.Any downsides? What about reasons?
Though many NTSC patched PAL ROMs work just fine, you should definitely avoid NTSC patching and rather use a real NTSC version. Timings can be off and gameplay and/or music could run too fast. Glitches might also occur that can be game breaking (e.g. Donkey Kong Country 2). For reasons on why you should prefer a PAL version over NTSC, look up for regional differences. You may leave a message here on how well certain games work, but I WON'T be able to fix any problems that occur due to the change. Also, if you don't know why you should use any of these, please ignore them.Feel free to give feedback, ask questions and report anything I messed up.Here is an abstract of the readme file on how NTSC patching works:
In either 7FD9 (LoROM) or FFD9 (HiROM) the destination code is stored (assuming a headerless ROM). NTSC patches set the destination code to 01. This is all and is pretty much what emulators do, when you force a ROM into NTSC mode.
ZSNES: set checkbox on ROM load ("Force NTSC")
Snes9x: copy "NTSC = TRUE" into [ROM] section of snes9x.conf
Most games do not trigger a regional lockout upon forcing NTSC mode, but there are many games that do. For removing a region lock, SNESTool is the most reliable and ucon64 did it's job on a couple of games. Both tools are included.
