1 year ago Hi. Here is all the info I have on CTR:
Character indexes: 0x0 - Crash Bandicoot 0x1 - Dr. Neo Cortex 0x2 - Tiny Tiger 0x3 - Coco Bandicoot 0x4 - N. Gin 0x5 - Dingodile 0x6 - Polar 0x7 - Pura 0x8 - Pinstripe 0x9 - Papu Papu 0xA - Ripper Roo 0xB - Komodo Joe 0xC - Dr. N. Tropy 0xD - Penta Penguin 0xE - Fake Crash 0xF - Nitrous Oxide (game locks up)
Unsupported indexes (0xF and up) lead to game crashing. If the index is 0xFFFF save is not active.
Save structure information: Values are stored in the little endian byte order.

Checksum calculation:

//Checksum calculation for (uint i = 0; i < 5760; i++) { r5 = InputData[i + 0x180]; r3 = 0x7; r7 = 0x10000; r6 = r7; r6 = r6 | 0x1021;
//Erase old checksum InputData[0x17FE] = 0x00; InputData[0x17FF] = 0x00;
while (r3 < 0xFFFF) { r4 = r4 << 0x1; r2 = r5 >> (int)r3; r2 = r2 & 0x1; r4 = r4 | r2; r2 = r4 & r7;
if (r2 != 0) r4 = r4 ^ r6;
r3 = (r3 + 0xFFFF) & 0xFFFF; } } return r4; }
Hi! Reading the source code I noticed it's set up to include display/editing of adventure mode stats (trophy, tokens, relics, etc..), but this stats are not sourced from the save file. Does anyone have a clue on how they are stored? I wasn't able to figure it out by myself nor did I find related documentation online. On the other end I was able to extract time trials and relics lap times from the save file. I think it would be nice to include all these features in the plugin! Thanks for the help!
