R-Type III - The Third Lightning notes

TODO: Add all relevant RAM addresses to observe, get all HP values for each relevant boss part, see if HP is higher on the 2nd loop, find more accurate partial beam charge damage, find other remaining damage sources
This is a resource page for R-Type III, developed by Irem and released in 1993 in Japan and 1994 internationally. Developed two years after Super R-Type, R-Type III has substantially less lag (though still present in situations) and more variety across the board.

Regional Differences

Boss HP values

Some bosses have multiple parts or phases to destroy. WRAM values are 2 bytes unsigned and little endian.

Stage 3 - Course Crab??
Stage 4 mid boss - Recojunator??

Damage tables

While the individual forces have names for each of their special weapons, the color will be listed first for clarity. Force damage also assumes the force is at power level 3. Damage numbers for most weapons tested on the 1st boss, Guard Ray.
Beam charge level times can vary slightly depending on the last shot type fired.
Damage types can't overlap. If the force is too close such that it's doing contact damage, it can cause some shot damage to be ignored. Good spacing will take out bosses faster for most weapons.
