Patches for Boot Sector Games for Cheating

Boot Genie works on many 512-byte Boot Sector game titles for archaic x86 systems with proper BIOS support. Most effects are created to be valid at the same time.

Introducing Boot Genie Game Ehnhancer for Boot Sector Games

With Boot Genie, you can patch certain game-play features and create special effects on a selection of available Boot Sector games found on the github ecosystem. These patches will change the original source, if you want to revert, just note the patches you have made and re-run them all with the -R option to 'patch.' You could also re-clone/update the repo as well. These patches use the standard 'patch' utility found in most *nix platforms

Patching

run the patch utility and redirect in the patch. For example, if the game is tetranglix and you want to apply the time cheat, then patch the source with the following command: patch < tetranglix_time.patch

Reverting to the original source by removing this particular time cheat is as easy as: patch -R < tetranglix_time.patch

Re-Assemble

Note that you are patching the source file, not the game image. You must reassemble the patched game in order to see your effects. An example of reassembling the tetranglix game after patching is the same as if you were to assemble it for the first time. One example with nasm is as follows: nasm -f bin tetranglix.asm -o tetranglix

Playing

You can then flash to a real floppy drive or emulate in things such as Virtual Box and Qemu. A Qemu example of running one of these games after patching is: qemu-system-i386 -hda tetranglix

Code Symbols

There are several types of codes that you can use to enhance the game-play elements with Boot Genie patches. Below are some quick visual cues as to what the code may do, and each code in the individual game sections will have further descriptions.

- Invincibility
- Harder Difficulty
- More Lives
- Speed Modifications
- Time Modifications
- Score Modifications
- Rule/Logic Changes
- Multipliers
- Color/UI Changes
- Better/Improved Powerups
- Level Changes

Patch Tips

• Try to keep patched version same amount of lines of code if possible, this allows for patches to be applied all at once and to not interfere with other patches/cheats.
• The actual command I use to create a patch: diff -u game.asm game_feature.hak > game_feature.patch
