I don't have time to filter this properly and debugging the PSX CPU isn't exactly a fast process when you're using M.E.S.S., so I did it the ghetto way.

Unfortunately another side effect is that PSX-Jin's "gui.box" function causes slow down when larger boxes get drawn, theres now way for me to fix it, but for the most part it runs full speed (just don't cast richters ricochet ball super lol, full screen hitbox causes 5fps).

PSX-JIN-rr is required and can be obtained here:

http://psxjin.googlecode.com/files/psxjinv2.0.2.zip

Script:

http://pastebin.com/a8VCEbKz

BLUE = Player vulnerability
GREEN = Player subweapon and sub attacks (like richters special moves)
WHITE = Player attacks (whip/swords etc..)
RED = Everything else (enemies, candles, etc...)

Enjoy!

You can toggle the HP display on enemies by setting the top line in the script to 'true' instead of 'false'. I turned it off by default because someones its hard to see the boxes with the HP text overlaying it.

Mecha, now is your chance to document the frogs. Good luck.

I can't wait to document the frogs! Someone said it didn't work on the PSX version, but they only tried it on the Rock Knights, so there's still hope.

And look at Richter's slide kick hitbox. Wtf. No wonder I usually end up getting hit instead sometimes.

I would also like to point out how awesome you are at doing this!

Any chance of a tutorial on this so other games can have a similar script? Metal Gear Solid for example.

Gotta learn assembly if you wanna find the hitboxes.

^ This.

There is no write up or tutorial I could provide because all games are different. These were found quickly because Konami was nice enough to code and store the object x/y positions, x/y radius, and x/y offsets into memory inside the object structure. Rarely do you get this lucky when dealing with hitboxes. The hard part for this game was finding the enemy structure size and when it began, I used M.E.S.S. and pSX for that. Games like metal gear solid will probably use a different hit detection system since they deal with 3D collision boxes and would most likely be even more difficult.

So I found most of the slow down in psx-jin with the viewer on comes from the fill on the boxes, so I updated the link in the first post that has a fill option toggle. It's set to transparent by default which would mean boxes would only have outlines. If you want the fill back just set the 'local transparent = true' at the top to 'local transparent = false'.

WHOA WHOA WHOA! This game was coded?

It was programed by a bunch of monkeys that were flinging marbles at a keyboard.

Mecha Richter has been getting hit by Frogs in the waterway in VERY weird positions. Like, he could be half-way off the screen and the frog would've still hit him due to a bug.

Should be noted that bug only exists in the XBL version.
