i thought of something interesting today while playing IIDX gold on PCSX2
the emulator inputs weren't actually that bad to me audio sync seem really good this time around compared to when i last played it
it made me think about frame rate logic for the PSX and PS2 games and the way their inputs are tied to frame rate
like Beatmania IIDX 3rd through 8th might actually have the same frame rate logic as their arcade versions due to how MAME has documented the BEMANI twinkle system and it's refresh rate logic when i apply the same logic to PCSX2 for the 3rd through 8th style CS versions i went activated Advance options in PCSX2 changed the default refresh rate from 59.94 to 59.82 which solved a lot of desync issues like early drifting same with IIDX 9th through gold it's somewhat documented that the arcade versions run at 59.95 hz which same thing but it seemed to fix desync issues for me i didn't use any hardware rendering i just use software with 3 threads.
it makes me really wonder if the frame rate logic from the arcades that came to consoles are meant to run at the arcade frame rate logic even for BEMANI games that aren't IIDX do they have the same refresh rate logic as like DDR 1st through extreme or supernova and Supernova 2 and pop'n games beatmania 5key and more that came to PSX or PS2. i wonder if they use DDR X US CS engine in AC DDR X since DDR X US CS came out before the arcade version and does it apply to US X2 CS with frame rate logic tied to music sync and can that be mostly elevated in Emulation i don't know about any other system since those seem to run on different engines and DDR main entries from AC like 1st through X got ported.
it's something i am thinking about
hopefully i am not annoying anybody but have a nice day
