# 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
|
||
|
|
```c
|
||
|
|
HW_REG(VI_CONTROL_REG, u32) = s1->features;
|
||
|
|
```
|
||
|
|
to
|
||
|
|
```c
|
||
|
|
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 `#include`s 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
|
||
|
|
```c
|
||
|
|
if (gConsoleType == CONSOLE_N64) {
|
||
|
|
```
|
||
|
|
directly after the `__osSiGetAccess` call.
|
||
|
|
|
||
|
|
Add
|
||
|
|
```c
|
||
|
|
} 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"`.
