GZDoom

• Emulator: GZDoom
• Folder: roms/gzdoom/
• Accepted ROM formats: .wad, .iwad, pk3,.ipk3, .zip or .7zip

No GZDoom emulator in Batocera needs a BIOS file to run.

Place your GZDoom ROMs in /userdata/roms/gzdoom/.

.WAD and .PK3

Each game needs a .WAD (Where's all data?) or .IWAD (Internal WAD), it's the main resource file for a Doom-engine game, containing all the game's original sounds, levels, and graphics.

Some files have conflicting names; ZDoom provides you with possible aliases.

.IWAD and .IPK3

In addition, some “total conversion”-type mods, can be played as their own IWAD; an IWAD is actually identified by its content rather than its name.

In order to play a custom level designed for any of the above games you have to have that particular game's full IWAD. If you do not have the necessary IWAD, you will get an error message on startup.

Custom IWADs can be detected. These custom IWADs need to have the .iwad or alternatively .ipk3 (not the traditional .wad and .pk3) extension, and they need to include an IWADINFO lump.

IWad: {

Name = "My Kickass Custom Game"
AutoName = "MyCustomGame"
Game = "Doom"
Config = "Doom"
StartupType = "Hexen"
BannerColors = "ff ff ff", "c9 00 00"

}

.ZIP, .7ZIP, .PK3 or .PK7

The PK3 file format is the same as the ZIP file format, and is treated exactly the same by ZDoom.

• EDuke32 allows you to choose between two different hardware accelerated OpenGL renderers, or the classic, warped software mode you grew up with

• EDuke32 adds a full-featured console, including Quake-style key bindings, command aliases, advanced tab completion, comprehensive command history, colored text and more
• EDuke32 has hundreds of code rewrites, optimizations and fixes for rare or annoying bugs in the original code

[Needs review]

Standardized features available to all cores of this emulator: eduke32.videomode, eduke32.padtokeyboard, eduke32.videomode, eduke32.bezel, eduke32.bezel_stretch, eduke32.hud, eduke32.hud_corner, eduke32.bezel.tattoo, eduke32.bezel.tattoo_corner, eduke32.bezel.tattoo_file, eduke32.bezel.resize_tattoo

Here are the default Eduke32's controls shown on a Batocera Retropad:

• Check logs files es_launch_stderr.log and eduke32.log at userdata/system/logs
• Make sure all files are available at roms/eduke32
• Make sure the .eduke32 launch file is setup correctly
  • Check the case sensitive
  • Check the use of FILE, FILE+ and CON
    • FILE and FILE+ must use the path /roms/eduke32/<gamefolder>/<main file or add-on>
    • CON also use the path /roms/eduke32/<gamefolder>/<con file>
  • .eduke32 files mustn't have empty lines, so delete the empty lines
• As a last alternative, reset system files: delete files from /userdata/system/configs/eduke32/* and /userdata/saves/eduke32/*
