How many should there be per frame? - -- Coin 2 doesn't work? DIP switch setting? - -- Protection: - I can see it reading things like the R register here and there, so it might - be cycle-dependant or something. - - 'Crash 1' checks I was able to see: - PC = $52FA - PC = $507F - - 'Crash 2' checks I was able to see: - PC = $54E6 - -Stephh's notes : - - - Coin 2 as well as buttons 2 to 4 for each player are only read in "test mode". - Same issue for Dip Switches 0-7 and 1-2 to 1-6. - Some other games on the same hardware might use them. - - Dip Switch 0 is stored at 0xf0ac and Dip Switch 1 is stored at 0xf0ad. - However they are both read back at the same time with "ld hl,($F0AC)" instructions. - - Dip Switches 0-0 and 0-1 are read via code at 0x9470. - This routine is called when you made a "line" after the routine that checks the score - for awarding extra help and/or changing background. - Data is coming from 4 possible tables (depending on them) which seem to be 0x84 bytes wide. - Table 0 offset is 0xeaf7. - IMO, this has something to do with difficulty but there is no confirmation about that ! - - Dip Switch 1-0 is read only once after the P.O.S.T. via code at 0xa200. - It changes (or not) the contents of 0xf0db.w which can get these 2 possible values - at start : 0x47a3 (when OFF) or 0x428e (when ON) which seem to be tables. - If you set a WP to 0xf0db, you'll notice that it's called more often in the "demo mode" - when the Dip Switch is ON, so, as it implies writes to outport 0x50b0, I think it has - something to do with "Demo Sounds". - I can't tell however if setting the Dip Switch to OFF means "Demo Sounds" OFF or ON ! - -Grndtour: - - Title should flash 3X slowly.
