(Note) They has to be Very Small AP in the Games for this Tutorial - It's just loading information First this is about rom loading information From what I have worked out and understand of - They is a Cretin patten in extinfo that would allow a game to load if The information in infolib.dat is also correct - They are two vital parts of the loading information, Hear they are This is what you should understand and shown witch offsets need the change - They are Cretin ones not to touch We also need DeSmuME emulator tool for the Job - Grate tool to have! Example 0x020D3380 - Changes in RAM for Each Game, I will show you how to locate this "later" for each ROM in RAM Arm9 memory with DeSmuME - use view memory In the RAM the HEX will be to find 38 40 2D E9 00 0C A0 E1 21 24 80 E1 The Patch over this will be 00 0C A0 E1 21 04 80 E1 00 10 A0 E3 The next offset that is "important" also both work together with the first offset - Either any of these - It's ok to have them all in the extinfo.dat file As a tester - eliminate ones later 0x02380668 - 0x023806B8 - 0x023807F0 - 0x023807C8 - Hex Patch for all listed 00 00 A0 E1 0x02380850 - Hex Patch 00 E0 C0 46 These will work with the first offset listed ^ (Note) If Hex start's at with DeSmuME 0x02000000 - Then we start at that, point in extinfo.dat 0x02004000 - Then we start at that, point in extinfo.dat This is ARM9 Area OK work out so far (Note) The offsets do have to be in this pacific order, are the game will not load fully - just black or white screens - sometimes it dose load with the two main offsets and infomation in infolib correct CODE 0x020D3380 - change-es for each ROM in RAM as noted abouth ^ 0x0233A1A8 - Unsure of what it does - but same for each rom listed in extinfo.dat remains the same!? - don't touch 04 4A BA 42 02 D1 80 22 92 00 BF 18 01 A2 17 60 4F 60 0D E1 FF FF FF FF FF FF FF FF 0x0233A3D4 - Unsure of what it does - but same for each rom listed in extinfo.dat remains the same!? - don't touch 0A 60 E7 E6 0x02339FA8 - Unsure of what it does - but same for each rom listed in extinfo.dat remains the same!? - don't touch 94 E8 3F 02 0x0233A2D8 - Unsure of what it does - but same for each rom listed in extinfo.dat remains the same!? - don't touch 85 42 3A E0 0x0233A228 - Unsure of what it does - but same for each rom listed in extinfo.dat remains the same!? - don't touch B8 20 00 23 88 60 CB 60 01 4A 01 3B 13 60 01 E0 B8 E8 3F 02 0x02380668 - changes but could use all - AS listed abouth ^ 00 00 A0 E1 0xC2339E40 - Unsure of what it does - but same for each rom listed in extinfo.dat remains the same!? - don't touch F8 B5 04 1C 0x02339E50 - Unsure of what it does - but same for each rom listed in extinfo.dat remains the same!? - don't touch 09 E0 55 4F 0x02339E70 - Unsure of what it does - but same for each rom listed in extinfo.dat remains the same!? - don't touch 4B 48 53 21 0x02339ED0 - Unsure of what it does - but same for each rom listed in extinfo.dat remains the same!? - don't touch 43 1C 03 E0 0x0233A50C - Unsure of what it does - but same for each rom listed in extinfo.dat remains the same!? - don't touch 03 E0 00 21 0xD0000000 - Don't know? - could be a barrier between ARM9 offsets Debugger patches after this for cretin Games How to locate first known offset with DeSmuME 38 40 2D E9 00 0C A0 E1 21 24 80 E1 Patch Hex 00 0C A0 E1 21 04 80 E1 00 10 A0 E3 Ok so we do a search - but use with the least hex in RAM very little of - Do a RAM Search with DeSmuME RAM Search - Take 21 24 80 E1 Reverse order the HEX E1 80 24 21 Tick - Equal to - DATA Size 4 bytes - Hexadecimal - Specific Value - E1802421 Then do a search - we have 020D3388 - Minus 8 = 020D3380 - Then do a Memory search of the Offset Address Now we have found the Correct ARM9 Hex to Patch, for extinfo! Applys to most ROM's Anyover thoughs ? Edited by drwhojan, 02 December 2010 - 12:23 PM.

GBAtemp Advance Fan Group: Members Posts: 597 Member No.: 221,134 Joined: 08-October 09	drwhojan, To correct you...If a game does NOT have any AP, then an extinfo entry is NOT required for that game but 99.9% of new games do require extinfo entries. The above 13 entries can be classed as 'MINOR AP' as the DSTT requires them to assist infolib and allow certain games to save correctly and stop freezing in games. As for infolib, no, I do NOT use any tool to find the data. OPTIONS.SYS is part of the TTMenu firmware.

QUOTE(drwhojan @ Dec 2 2010, 04:13 AM) <{POST_SNAPBACK}> Lol, phoenixgoddess27, patience about two years XD! bumping is easy done if click on rong box That made no sense. You didn't choose the wrong box. I read what the post said before you removed it, it was related to this. You're pretty known for doing things like this. Anyway, hope you figure out what it is you're trying to figure out.
