Rough draft

psfour2pstwo

possible speed/comp hacks

• --detect-idle-vif
• --detect-idle-ee
• --detect-idle-iop
• --detect-idle-intc
• --detect-idle-chcr

other

• --force-point-sampling
• Project Snowblind US mipmap offset 0019506C bc1f loc_19508C

vu

Looks like VU sync always(?), not like ps2.

todo

• convert from [pre] to native wiki table: https://www.psdevwiki.com/ps4/PS2_Emulation#Memory_Mapping
