Manual application of ISXPM patches

This manual patch applier was originally made to apply ISXPM (Inno Setup XDELTA Patch Maker) game patches. It is extremely useful in a scenario when ISXPM patch mismatches in one or several resulting files and then rolls back whole patch.

Playing GTA IV with achievements

PC version of GTA IV was originally shipped with Games for Windows Live (GFWL, later Xbox Live) achievements. In latest Complete Edition GFWL was removed and replaced with Rockstar Games Social Club (RGSC) and Steam achievements. This guide will help you to play whatever version of GTA IV you might have with achievements. 

Obviously this guide is not for legit game which already has Steam and RGSC overlay with achievements. However, legit game users still might find this guide useful.

Popular scenarios

1. Playing Complete Edition fully offline using custom achievement overlay
2. Playing downgraded 1.0.7.0 or 1.0.8.0 version offline with achievements
3. Playing Complete Edition on Steam without Rockstar Game Launcher using native Steam overlay 

Corrupted savegame in GTA IV

How a save gets corrupted

It is related to modding or using a trainer. 

I got a corrupted save after 25 missions (after Roman’s Sorrow) when I was making a Russian translation of mission names frequently modifying .gxt file and using SNT’s Mission Help a lot. 

How to know if your savegame is corrupt

Symptoms of a corrupted savegame are:

Универсальная русификация GTA IV, EFLC, Complete Edition

Для чего вам может понадобиться данная русификация

• Вы используете EFIGS версию игры, которая хорошо поддерживает нужные вам моды (например, для локализованных версий GTA IV и EFLC сложно найти scripthook, а также многие кастомные .asi моды поддерживают только наиболее популярные EFIGS-версии GTAIV.exe и EFLC.exe);
• Вам не нравится мат и корявые названия миссий в других самопальных переводах этой игры;
• Вы не знаете английского и хотите русские названия миссий;
• Вы знаете английский, но в последнее время западное вам как-то не катит, и вам хочется чего-то необыкновенно богатого, великого и могучего.

Особенности пакета

• Поддержка всех EFIGS и локализованных RUS версий GTA IV и EFLC включая последнюю Complete Edition
• Русификация интегрированных GFWL эпизодов TLAD и TBOGT в базовой игре GTA IV

Why no "Shweine" at the start of GTA IV?

The first song playing in Roman’s car at the start of  GTA IV is "Schweine" by Glukoza. However, during recent playthrough I didn’t hear it so I researched this issue using Parik’s AudioMetadataTool. 

Here’s why you may not hear the song

1. You have latest Complete Edition with cut radio

How to downgrade GTA IV Complete Edition to EFLC

So you've got latest GTA IV Complete Edition on Steam/Rockstar Launcher or Fitgirl repack and you want to turn it into original binary-identical EFLC (Episodes From Liberty City). This downpatch made in ISXPM in conjunction with official Rockstar EFLC Patch 2 or 3 (both included in the package) does just that.
