// Glide64 - Glide Plugin for Nintendo 64 emulators (tested mostly with Project64)
// Project started on December 29th, 2001
//
// To modify Glide64:
// * Write your name and (optional)email, commented by your work, so I know who did it, and so that you can find which parts you modified when it comes time to send it to me.
// * Do NOT send me the whole project or file that you modified. Take out your modified code sections, and tell me where to put them. If people sent the whole thing, I would have many different versions, but no idea how to combine them all.

Notes:
------
Setting the approprate bits in the MI_INTR_REG and calling CheckInterrupts which
are both passed to the DLL in InitiateGFX will generate an Interrupt from with in
the plugin.
The Setting of the RSP flags and generating an SP interrupt should not be done in
the plugin
