Logging

Restore the game's built-in logging (log_restore)
Description	Very useful for debugging.
Address	v1.00c 0x475030
Code	e9 [log_printf] jmp [log_printf]

Textbox size

Correct text length calculation for Fairy Wars-style text boxes (fw_textbox_size)
Description	Same hack as for th128.

Code	90 90 56 e8 [GetTextExtent] 89c1 nop nop push esi call [GetTextExtent] mov ecx, eax

Spells

Spell card alignment (spell_align)
Description	The last three instructions would be unnecessary, but are, again, required for this to work with gensokyo.org's English patch.
Address	v1.00c 0x46e9cb
Code	ff75 10 c1e9 0c 83e1 01 51 ff75 0c ff75 08 ff35 10c34d00 ffb5 74ffffff e8 [GetTextExtentForFont] 83c0 08 50 db04e4 58 v1.00c 79 06 d805 b0ea4a00 dee9 push dword ptr ss:[ebp+0x10] ; Optimized original code shr ecx,0x0c and ecx,00000001 push ecx push dword ptr ss:[ebp+0x0c] push dword ptr ss:[ebp+8] push dword ptr ds:[th13.font_spell] ; Spell card alignment push dword ptr ss:[ebp-0x8c] call [GetTextExtentForFont] add eax,8 push eax fild dword ptr ss:[esp] pop eax jns short +6 ; gensokyo.org fadd dword ptr ds:[th13.4aeab0] fsubp st(1),st

Player data

Remove spell "alignment" in the result screen (result_spell_align)

Address	v1.00c 0x46eac3
Code	31c0 xor eax,eax

Compatibility

Remove English patch font creation (unpatch_fonts)
Description	At this position, the English patch jumps to its font creation code, located in th13e.dll. Since we don't patch the import table of this DLL, its CreateFontA calls are still mapped to the actual system function, effectively ignoring thcrap's own font settings. This hack simply re-inserts the original game code from that position.
Address	v1.00c 0x45ad24
Code	68 e4cc4a00 6a 11 6a 04 push th13.04acce4 push 11 push 4

Remove English patch replacement for the resolution dialog (unpatch_dialog)
Description	Come on. You could have just replaced the pointer directly instead of ripping out the original function call and replacing it with your dummy function that... replaces the pointer. -.-
Address	v1.00c 0x45c3a1
Code	ff15 f8214a00 call [DialogBoxParamA]

Remove English patch text formatting tag parsing (unpatch_layout)
Description	It's not because we don't like your formatting tags, it's because you don't give us any chance to parse our own... which requires the exact absence of any binary hacks jumping into a different module. And well, pixel definitions are just not the way to go for an open, multilingual system.
Address	v1.00c 0x45afbe
Code	75 77 8b4d 18 51 56 ff15 18204a00 8b45 0c 53 03c0 57 8945 e4 6a 04 83c0 02 50 jnz short +0x77 mov ecx,dword ptr ss:[arg.5] push ecx push esi call [SetTextColor] mov eax,dword ptr ss:[arg.2] push ebx add eax,eax push edi mov dword ptr ss:[local.7],eax push 4 add eax,2 push eax

Hardcoded strings

One hack per hardcoded string. Wonderful!

Address	v1.00c Rx53ced
Code	68 4cc84a00 push th13.004ac84c
