So far i tested Radirgy/Ibara/Mushihimesama/Psyvariar 2 (Ibara and Mushi were tested because of their arrange modes, though having high quality music may make some people try playing on these ports instead of fbneo), and all of them have 2 to 3 frames of internal lag by default, alongside external latency being minimal, which is fairly weird as external latency made flycast unplayable and makes CV1000 games require runahead to work properly.

Was pretty much just testing run-ahead values on CV1000 games (all of which seemed to have only 2 frames of internal lag, meanwhile external lag was somewhat inconsistent) and well... accidentally did a 1-ALL of DFK with B-Bomb.

Tons of horrible autobomb triggers, 2 deaths before stage 5, and countless missed bees... Even though this one can be excused for as "trying to stay on Omote route". Well, at least now i have unlocked strong style ships the legit way, so whatever.

Got it like, after 2-3 restarts. Guessing combination of pad change (previous pad that mushi 1.5 original 1cc was done on was some switch pro pad replica) with slightly improved skills at reading faster bullets (thanks to shienryu) have made it much easier for me.

This being said, this run is fairly weird, and can also be taken as a lesson on why you should avoid restarting:

Stage 2 boss went a bit messy (panic bomb, which is something i don't do at all) and a VERY AWFUL death with 3 bombs on stage 3,

HOWEVER after that i no-miss rest of stage, do VERY AWKWARD dodging on stage 3 boss during one of patterns that i prefer bombing it out, no-miss entire stage 4 (and no-bomb midboss), and then go into stage 5 with 4 extends!

At this point i knew 1cc was secured, since all the extra lives allow me to make few mistakes during stage with minimal consequences, i was fairly confident in making it into last boss with enough resources to shamelessly spam the FUCK outta this guy.

Truly a weird run...

Delay there is fairly huge (like, RA Flycast levels of delay) but game is playable due to easier difficulty. Was pretty close to 1-miss too, if not for lobotomite death on stage 5 and death on Yuuka's yellow spam (which i'm sure you can safespot from above but i'm too lazy to do that)

Planning to either no-miss or at least low-miss the game.

Recently tried playing some of PC-98 Touhou games through DOSBox-X, and I SWEAR the input lag there is MASSIVE. Any suggestions on how i could improve the latency issues?

Title explains itself.

Flycast is too laggy to be comfortable with high speed ship and seems to be lacking any slowdown. Does dolphin/pcsx2 perform any better? I also heard newer consoles have gotten Radirgy ports too (however i'm not sure of that), so those can be an option too.
