// These games have an issue where if a vblank interrupt occurs at the wrong moment, it can interrupt a function that is
// using a global struct and then modify that struct, which causes the game to softlock when the vblank handler returns.
// This is claimed to be due to a circular buffer used for texture loading. The patch rewrites the function to use a vblank wait.

// MetaFortress games below here.
//
// MetaFortress is an automated system that replaces the typical way DS games are built. It automatically injects
// code inside developer-written game functions that conducts checksums on other functions, including SDK functions
// and also other game functions that previously were modified with injected checksum calculations.
// The checksums themselves are randomized: the way they load pointers, access data, update the checksum state,
// perform a checksum finalization, and compare the calculated result to the expected result, as well as what happens
// if the checksum fails, are all subject to a high degree of randomization that makes automated static analysis
// difficult or impossible.
//
// This is in stark contrast to DS Protect, which had no per-game randomization (except for The Legend of Zelda: Spirit Tracks)
// and required each invokation and response behavior be manually programmed in.
//
// For example, a basic game function like this:
//
// void gameFunc(...)
// {
// /* Game func stuff */
// }
//
// May be transformed into something like this:
//
// void modifiedGameFunc(...)
// {
// u16* start = ((u16*)0x02013458) + 0x200; /* Some target range, +random offset */
// u16* end = ((u16*)0x020140B0) + 0x200;
// u32 checksum = 0;
// do
// {
// checksum ^= start[-0x200]; /* Load from inverse offset, add to checksum */
// checksum *= 113041; /* Update checksum, random operation */
// }
// while (++start != end);
// checksum ^= checksum >> 7; /* Finalize checksum, random procedure */
// checksum += checksum << 2;
// checksum ^= checksum >> 13;
// checksum += checksum << 5;
// if (checksum == 0xFBD4230) /* Compare checksum, correct value is often loaded off the stack */
// {
// /* Game func stuff */ /* Normal game procedure */
// }
// else
// {
// /* Game crash */ /* Crash somehow, randomized assembly(?) */
// }
// }
//
// The game crash itself is heavily randomized, often assembling an address with obfuscated arithmetic
// and then branching to it, sometimes jumping multiple times before eventually entering an infinite loop.
//
// MetaFortress games typically do this to approximately 200 game functions. Some have 100 or fewer checksums, while others
// have over 300. The number of functions to modify, as well as performance-critical functions to avoid modifying, were
// controllable by the game developers.
//
// However, only 8 games, 18 if you count regional releases, utilize MetaFortress. The majority of them are Ubisoft games.
//
// To patch MetaFortress, the comparisons between calculated checksums and expected checksums are replaced with "cmp r0, r0".
// The list of addresses below are where these compares occur (if Thumb, +1 to the address).
