iQue Player Support Enhancement

This enhancement allows the same ROM to work on both the N64 and the iQue Player.

Instructions

Fix video corruption

In lib/src/__osViSwapContext.c, change the line

HW_REG(VI_CONTROL_REG, u32) = s1->features;

to

HW_REG(VI_CONTROL_REG, u32) = s1->features & ~(1 << 13);

This has no effect on the N64, but prevents video corruption on iQue. Games will be unplayable on iQue unless you do this modification.

Add console detection

Copy enhancements/ique_support/skGetId.s into lib/asm/.
Copy enhancements/ique_support/consoleType.c into lib/src/.
Copy enhancements/ique_support/console_type.h into include/PR/.

Add the line #include <PR/console_type.h> to the bottom of the block of #includes in include/ultra64.h.
Add the line gConsoleType = get_console_type(); as the first line of code in osInitialize() in lib/src/osInitialize.c (i.e. right before the line D_80365CD0 = TRUE;)

Patch libultra EEPROM functions

Console detection needs to be added for this modification.

In lib/src/osEepromRead.c, lib/src/osEepromWrite.c, and lib/src/osEepromProbe.c:

Add

if (gConsoleType == CONSOLE_N64) {

directly after the __osSiGetAccess call.

Add

} else if (gConsoleType == CONSOLE_IQUE) {
#include "../../enhancements/ique_support/FILENAME.inc.c"
}

directly before the __osSiRelAccess call; replace FILENAME with the filename, i.e. if lib/src/osEepromRead.c put #include "../../enhancements/ique_support/osEepromRead.inc.c".
