Lots of FP hacking for little gain, super monkey ball is only slightly more sane (wow, it rhymed). Temporary no-speed-limit hack: Hold TAB.

// SUPER MONKEY BALL IS BEING A ROYAL PAIN
// We are missing the caller of 800070ec
// POSSIBLE APPROACHES:
// * Full SW FPU. Urgh.
// * Partial SW FPU, emulate just as much as necessary for monkey ball. Feasible but a lot of work.
// * HLE hacking. Figure out what all the evil functions really do and fake them.
// Interesting places in Super Monkey Ball:
// 80036654: fctwixz stuff
// 80007e08:
// -98: Various entry points that loads various odd fp values into f1
// 800070b0: Estimate inverse square root.
// 800070ec: Examine f1. Reads a value out of locked cache into f2 (fixed address). Some cases causes us to call the above thing.
// If all goes well, jump to 70b0, which estimates the inverse square root.
// Then multiply the loaded variable with the original value of f1. Result should be the square root. (1 / sqrt(x)) * x = x / sqrt(x) = sqrt(x)
// 8000712c: Similar, but does not do the multiply at the end, just an frspx.
// 8000716c: Sort of similar, but has extra junk at the end.
//
//
// 800072a4 - nightmare of nightmares
// Fun stuff used:
// bso+
// mcrfs (ARGH pulls stuff out of .. FPSCR). it uses this to check the result of frsp mostly
// mcrfs (ARGH pulls stuff out of .. FPSCR). it uses this to check the result of frsp mostly (!!!!)
