What is a Speed Modifer? A speed modifier alters processing speed of your PS2 Unit. Some Speed Mods alters the speed of the actual game you are playing. What is the purpose of these codes? Nothing really. If stuff people do in there spare time, and its really help for the games that load so slowly. Lets give them a Boost! This is not a complete guide! this is just to give you the general idea of what to look for when trying to make this codes. Here is a tip when looking for a Speed Mod, Load the elf, and invoke analyzer in PS2DIS or if you use IDA Pro let it load completely or until it lets you exploder the file, just do a search for 3f800000 (0000803f) Yes there will be alot of 3f800000, but this narrows it down since 3f800000 equals the default speed of the game. -=- Values -=- 1xxxxxxx ???????? 00004000 Super Speed 00004080 Turbo Speed 00004100 Ultra Speed 00003F80 Normal Speed (Default) 2xxxxxxx ???????? 3E400000 Mega Slow Motion 3E800000 Super Slow Motion 3F000000 Slow Motion 3f800000 Normal Speed (Default) 40000000 Hyper Mode 41000000 Mega Hyper Mode 40800000 Super Hyper Mode -=- Patterns =-= This is the most difficult, but this is th most widely used method in finding the codeunless you ahve a trainer or dumper. First thing you want to do is know what pattern to look for, common sense is look for the default speed 3f800000. So you are going to look for the pattern 0000803f as a hex stringer For Future Reference cause i know some people will not get it 3f800000 = 0000803f NOTE: that this is the hardest method of them all! =-= Labels/ Symbols -=- Game games will have a label so well covered up you could be looking at it and not even think to use it. Some games could just flat out say game Speed like Trigger Man whose label is gameSpeed gameSpeed 0027761c 3f800000 lui zero, $0000 Hyper Mode :) 2027761C 40000000 Slow Motion 2027761C 3F000000 One thing about Triggerman is that it's very well labeled, and you can many address that will give you the same effect. Here are some examples Dive always Slomo 00279a54 00000000 nop 20279a54 00000001 Throw always Slomo 00279a58 00000000 nop 20279a58 00000001 Slow Motion 00279b3c 00000000 nop 20279b3c 00000001 * All TriggerMan codes made by GMO Some Games will take more looking into and test, especially RPGs I'll take Xenosaga as an example wee start out looking through the elf for symols such as gameSpeed since i didn't find any reconize symbols i'll try the default speed value and we come across some labels such as rate.0 and rate.1 lets test them out. I see a lower value in there also, but we don't want no slow ass shit in the code! rate.0 00364910 3f800000 .word $3f800000 00364918 3f000000 .word $3f000000 Hyper Mode 20364910 40000000 20364918 40000000 Testing... Works! =-=Disabling Sub-Routines-=- this were introduce by Nach Brenner of Xploderfreax there are three (3) Main Routines that are almost quaranted to work sceMcSync sceGsSyncV InvalidDCache | SyncDCache Disabling Routine 1. Load the Elf - File in PS2DIS or IDA Pro 2. Jump to Label sceGsSyncV, sceMcSync, and InvalidDCache | SyncDCache 3. Disable It with 03e00008 jr ra 00000000 nop or 03e00008 jr ra 24020001 addiu v0, zero, $0001 Example: Akira Psycho Ball NTSC-J sceGsSyncV 0013c600 27bdffe0 addiu sp, sp, $ffe0 0013c604 ffb00000 sd s0, $0000(sp) Faster Loading 2013c600 03E00008 2013c604 00000000 Example: GTA San Andreas NTSC 00548918 27bdffe0 addiu sp, sp, $ffe0 0054891c ffb00000 sd s0, $0000 (sp) 20548918 03e00008 2054891C 00000000 Result...
