Game Maker 8

The eighth version of the Game Maker game creator, no longer supported by the developers, but fully compatible with Windows 7, 8, and 10. Works perfectly with Xtreme3D and can open project files from older versions of Game Maker. The archive does not include standard sprites and other resources.

Note: Game Maker 8.0 does not support Game Maker 8.1 project files, prior conversion is required. Find the converter below. Additionally, some games may have issues running on Windows 10. We recommend using the gm8x_fix patcher, you can find it on this page below.

GM Game Converter

There's a common misconception that old GM games can no longer run on newer Windows, but that's not true. YoYo Games released a special patcher for EXE files compiled in Game Maker 6, which adds compatibility with Windows Vista and above. So, if you find a game that doesn't work, try using this converter. There's no absolute guarantee, but it works in most cases.

A 3D model converter for Game Maker-readable formats. Specifically, Marzipan supports importing VTX, OBJ, 3DS, and X files, and can save models to GM 6.0 and 6.1 scripts, ASCII DAT files containing vertex data, the well-known open OBJ format, HTML and XML tables, GML arrays, and a compact format convenient for storing collision models. It also offers a wide range of additional tools, including object transformation, a UV coordinate editor, batch conversion, and more.

MoveNow!

A program for skeletal animation of humanoid characters. It features a built-in skeleton, which can be used to create any sequence of movements. The bones rotate along all three axes and can also be lengthened and shortened to achieve various skeleton proportions. You can save the skeleton shape as an MSS (MoveNow Skeleton Shape) file. The finished animation is saved as an MNS (MoveNow Single Sequence) file, and a group of these files can be compiled into a single MNC (MoveNow Complete Sequence) file, which will be used in game.

It provides full export of GML 6.1 D3D models (MPV, MOD), GML 6.1 D3D model scripts (GML), and GML 6.0 D3D primitive scripts (GML). It supports viewing and exporting UV coordinate maps, smooth normal generation, and various model rendering modes. The archive includes the source code for Game Maker 6.

Particle Designer 2

At one time, this was the most powerful visual particle editor for Game Maker 6. It supports all GM particle components: particles themselves, emitters, attractors, deflectors, changers, and destroyers. It offers numerous settings for each component, plus the ability to write and test system code in the built-in text editor. It also includes tools for creating a random system, copying data to the clipboard, rendering static screenshots, and even animated GIFs. External particle sprites, hotkeys, fullscreen mode, and much more are supported. The resulting system can be exported as a GML script and used in-game. The author announced the development of a third version of Particle Designer for Game Maker: Studio, but this project appears to have stalled.
