Re: Doom 'MBF' for DOS, Maintenance release 2.04

 Changelog
Spoiler

COD10

• allegro.h replaced with the one built from MBF 2.0.4 souce package


COD10FIX

• engine now picks up assets wad (normally COD.WAD) from engine EXE directory, then from current directory if it was unavailable
• engine now picks up levels wad (CODLEV.WAD) from engine EXE directory
• non-printable chars are now properly filtered out from savegames names and other text input fields in the menu
• starting the game from the first new level in pwad works differently now for Doom 1:
- episode selection menu is shown always for Doom 1
- there's a menu item on episode selection screen called Load Wad selecting which starts the game at first changed level
- in case vanilla Doom 1 is loaded (i.e. no new levels in pwads) this item takes player to e1m1
- for Doom 2 (aka commercial) there's no episode selection screen (i.e. same behavior as before)

COD10MBF

• platform specific system startup routines replaced with those from MBF 2.0.4
below are details of what has been changed as a result
• graphical startup gone as a result although option for that remains in the menu
• tick to real time scale adjustment is still supported, but is not dynamic and required engine restart to be picked up
• video optimized assembly code replaced with that from MBF 2.0.4
• platform specific video mode and blitting code replaced with that from MBF 2.0.4
• VESA relared functions from MBF 2.0.4 have been incorporated
• video mode selection is gone, replaced with 3 options for controlling rendering and menus updated for that
- hi resolution mode
- page flipping enabled
- vertical trace is used
• benchmark option removed from menu as baselines for videomodes are gone with the modes (it did not seem to work anyway)
• incidentally platform specific keyboard and joystick code also replaced with one from MBF 2.0.4
• audio-device specific platform code and MUS to MIDI converter code replaced with those from MBF 2.0.4
• platform specific audio code interfacing Allegro lib replaced with that from MBF 2.0.4
• because of how sound setup works there, it is now longer possible to choose MIDI and digi card from the menu and control voice detection; instead setup.exe from MBF 2.0.4 package should be used, which creates setup.cfg that Allegro uses
• sound effects pre-caching at startup is no longer optional and happens always, so option to control it is gone from the menu
• connectivity related code has also been incorporated, however I have not really tested anything multiplayer
in addition to this

• "modern" MBF-style video mode and FPS counter overlay added (can't say I trust it very much though)
• in cases when engine believes that assets wad is called the same way as IWAD it detects (e.g. both called DOOM2.WAD) it will now be loaded only once
• restored graphical startup
• removed option to show disk in the menu as it's not something supported after MBF video code moved in
• engine will now persist smooth mouse turning option
• experimental changes to horizontal turning with mouse

Hey, @DosFreak

Just a heads up this port has been given a name to distinguish it from COD proper by Joel Murdoch, and underline the fact that it treats itself as a generic purpose source port. The name is Tartar and description is now available in documents bundled with source code: https://gitlab.com/ludicrous_peridot/cod10mbf … aster/README.md

I see MBF 2.0.4 mentioned a lot in the changelog. Is the new port completely MBF-compatible / based-on, or does it incorporate a subset of the features?

The port only incorporates platform specific code from MBF and then specifically from Gerwin's MBF 2.0.4. It is an Eternity Engine 3.29 fork.

Pardon the bump, but could this thread be renamed please. COD is a thing, and I dont want to cause any confusion with the Doom source port for DOS named Tartar which builds on COD legacy that this thread describes.

Edit: Thanks for the update.
