PS2 Patch Engine should work for the vast majority of PS2 titles, but there are some that are known to be incompatible Patch type 2 (word) can use any address which is a multiple of four Patch type 1 (short) can use any even address Patch type 0 (byte) can use any address Patches can only be applied to addresses which are aligned to their data size - this is a restriction imposed by the Emotion Engine (and nearly all CPUs) "Patch list contains misaligned writes".Not all cheat types are supported - see the Using patches section above "Patch list contains unsupported cheat types".
Note: While there is no explicit limit on the number of ELF patches that can be applied the total number of applied patches is limited to 1024 patches after 1024 will be ignored. PS2 Patch Engine can embed more than 100 patches per-executable into most games (the actual limit varies from game to game but the absolute maximum is 160), this error indicates that the number of memory patches exceeds the game's patch limit. One of the following errors may occur immediately after clicking 'Patch' or after selecting executables to apply patches toĮither no Mastercode was found (with 'Autohook' enabled) or PS2 Patch Engine was unable to locate the resources neccessary to embed a real-time patch engine If no patch format is selected or no valid patches were found then one of the following dialogs will appearĬlicking 'Yes' will create an unmodified copy of the image (although the image format can still be converted from."It's asked me a question.what do I do?".This was a ton of work (10,000+ lines of C) so I'm hopeful that it finds some use.The following dialog will appear and a new (patched) image will be created, press 'cancel' or close the window to cancel the operation.bin selecting "ISO image" in the "Save as type" drop down or changing the extension to. A 'Save As' dialog will appear asking for the file name of the new patched image.If a game contains multiple executables (ELFs) and a patch can be applied to more than one executable then one of following dialogs will appearĬlicking 'Remember selection' will supress future prompts where the selected options are available.Click the 'Patch' button to create a new patched image.Some Mastercodes which will work on CodeBreaker or ps2rd may still report this error.
One or more of the Mastercodes provided is either incorrect or the address referenced by the hook cannot be found in any executable (ELF) on disc.

In case of an error one of the following error messages will appearĪ RAW code with a type other than '9' was entered Enter one or more Mastercodes and press 'OK' to continue Mastercodes must be in RAW format and must begin with '9' (9 type 'hook' Mastercode) If 'Autohook' is disabled the following dialog will appear when applying memory patches to a game Unless patches are not working for a particular game this option should be left enabled Selecting the 'Autohook' check box enables automatic Mastercode determination.Selecting the 'PNACH' radio button interprets patches in PNACH format.Selecting the 'RAW Code' radio button interprets patches in RAW format.Not all cheat code types are supported!įor RAW: Code types 0, 1, 2 are supportedįor PNACH: 'word, 'short', 'byte' as well as 'extended' types 0, 1, 2 are supported.Patches can be in either RAW (unencrypted) or PNACH (PCSX2 cheat file) cheat code format.Drag and drop, copy and paste or click 'Browse' to add patches.Patched images are compatible with both PS2 emulators and real PS2 hardware and have been tested with PCSX2, OPL, ESR discs and the PS3's PS2 Classics emulator. Not all games will work but, based on analysis, compatibility should be better than 95%. Patches can provide widescreen support as well as controller remapping PS2 Patch Engine is a tool designed to embed both static (ELF) and run-time (memory) patches directly into PS2 disc images.
