What do the different FPse System options do?

[dabomb224]

I have taken the time to look over the FPse Android forum, as well as the manual that was written for the older Windows Mobile version, but neither of these really explain what the different choices in the options menu do.

These selections include:

- Mdec Acceleration
- Gte Acceleration
- Fast Booting
- HLE Mode
- Boost Mode

Anyone here know what these actually do?
