Summary	07896: raiden2 and clones: Score-based extends do not work correctly
Description	Extends are not awarded at the score set by the DIP switches. Extend pickups work as expected.
Steps To Reproduce	Start game, play until first extend score is reached. (Default is 200,000) No extend is given.
Additional Information	Investigating this, it looks like the game reads the extend score table from ROM, but the score it reads in 90,000,000. Using the debugger to alter either the score or the next extend value shows that the routine to check for extends is working properly. This may also affect raidendx, but the extend DIPs are listed at unknown. Curiously, test mode does not show extend settings.

PSX port (The Raiden Project) video doesn't have score extends on 200,000 score either. Needs the PCB video of Raiden II (to confirm that doesn't have score based extend)

No.18839 mahlemiut Developer May 12, 2021, 21:45	The extend DIP switch info comes from the Japanese manual. Changing the extend DIP switches does change the extend value, if I remember it right, to either 91M or 92M. That the values are EXACTLY 90M, 91M, 92M, etc, suggest that it is an intentional change.
