Ranma 1/2: Chougi Ranbu Hen is calibrated for 60 fps but can never reach it. The framerate varies continuously between 30 and 50 fps, in slow motion. The other consequences are a degraded input lag and a very bad frame pacing.

The hack consists of optimizing the code of the most expensive tasks (this is not a SA1 or FastROM hack). This goes from sprite management to collision management, including input management and sound effects, plus a few other little things. The result is a game that now runs with a rock stable 60 fps framerate. The input lag is also improved and the frame pacing is now perfect. Another fun side effect is that the timer now runs at the correct speed (99 seconds is exactly 99 seconds now, unlike the original game).

But this is not just a framerate improvement patch. It’s a double patch that also fixes a lot of collision bugs from the original game to have a cleaner game. I detail all the collision changes in a google doc (the link in the video or the readme) for pro players of the game who would like to know exactly what changes on this subject.

This patch is compatible with the Dynamic-Design’s translation patch V1.10 but it must be applied before the translation patch.
