Ranma 1/2: Chougi Ranbu Hen - Big Framerate Improvement

Hack of Ranma 1/2: Chougi Ranbu Hen

Description

Ranma 1/2: Chougi Ranbu Hen is a good fighting game close to SF2 but with one big flaw: Its framerate is catastrophic. The game is calibrated for 60 fps but can never reach it even if you don't touch the controller and leave the fighters idling. It varies continuously between 30 and 50 fps. With the way games used to work, this means that Ranma runs in slow motion all the time.
The other consequences are a degraded input lag and that the game also has very bad frame pacing because the duration of the frames themselves is very variable. It can vary from 1 to 4.

The hack consists on 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. There is no longer any frame drop even in the most extreme situations. It completely changes the pacing of the game. The input lag is also improved and the frame pacing is now perfect.

In addition, the patch also includes the correction of 4 collision bugs which very slightly change the behavior of collisions by improving precision.

This hack is currently incompatible with the translation patch. It’s not just a menu glitch issue: they overwrites each other’s data.

Update history:
Version 1.1: fixes a bug that causes the game to crash
