Minor modification for compile with CWC under Windows.
This generate an Win32 .exe executable file for game on Windows and Cpcdos OS2.1
Use adapted doom.cpc file for execute win32 game into cpcdos

Example on ElieOS on Cpcdos OS2.1 kernel
The purpose of doomgeneric is to make porting Doom easier. Of course Doom is already portable but with doomgeneric it is possible with just a few functions. The limitation is there is no sound!
To try it you will need a WAD file (game data). If you don't own the game, shareware version is freely available (doom1.wad).
Create a file named doomgeneric_yourplatform.c and just implement these functions to suit your platform.
- DG_Init
- DG_DrawFrame
- DG_SleepMs
- DG_GetTicksMs
- DG_GetKey
| Functions | Description |
|---|---|
| DG_Init | Initialize your platfrom (create window, framebuffer, etc...). |
| DG_DrawFrame | Frame is ready in DG_ScreenBuffer. Copy it to your platform's screen. |
| DG_SleepMs | Sleep in milliseconds. |
| DG_GetTicksMs | The ticks passed since launch in milliseconds. |
| DG_GetKey | Provide keyboard events. |
| DG_SetWindowTitle | Not required. This is for setting the window title as Doom sets this from WAD file. |
I have ported to Windows, X11, and Soso. Just look at (doomgeneric_win.c or doomgeneric_xlib.c).
Note that X11 port is not efficient since it generates pixmap by XDrawPoint. It can be further improved by using X11 extensions.
