Medal of Honor: European Assault PC Port

Medal of Honor: European Assault - PC Port 0.9.1-beta

Unofficial PC port made by statically recompiling the game (Xbox, USA / NTSC-U). No game files are included - you need your own copy (put DEFAULT.XBE, the DATA folder and EAGLRM.O in the game folder, then start Launcher.exe). The port’s source code is now published (MIT) in the source folder of the repository.

What’s new

Faster — measured, same PC, same settings

A/B test of the 0.9.0-beta executable against this one (RTX 4060, 165 Hz cap, same level, same route):

In the heaviest places of the author’s test (where 0.9.0 dipped to 80–125 fps) the new build stays above 150. Gains depend on your PC; the busiest scenes gain the most. What changed inside:

• The whole game code is built with profile-guided optimisation, trained on real play.
• The cached register and memory base addresses are loaded once per function instead of before almost every memory access, in all 21,741 recompiled functions.
• The game thread gets priority in the emulated CPU lock: a worker no longer holds it for milliseconds (waits fell from 5–6 ms to under 1 ms per frame).
• Environment-variable lookups answered from a per-thread cache (they were hit on every frame).
• A hitch watchdog and a per-second [FRAMES] line in play_log.txt (frame times, lock waits) so a stutter can be traced from a bug report.
• The developer diagnostics (AI probes, shot and projectile logs, aim measurement) are compiled out of the player build, so they cannot cost a frame.

Gameplay fixes

• Karabiner 98k (and the whole fast-rifle class) now hits what the crosshair is on at 60 fps and above. At high frame rates the game dropped the camera-kick term from the bullet’s direction, so the bullet left about 2° too high and passed over enemies at range, while at 30 fps it was fine. The direction is now the same at every frame rate. It applies to the player’s bullets with a fast muzzle speed (the Karabiner and rifles that share its class), not to machine guns or pistols. RECOMP_AIM_FIX=0 turns it off.
• Weapon mods: the scanner no longer reads mods\weapons\README.txt as if it were a weapon file.
• Grenade timer (new, on by default, switchable): a small circle at the side of the screen counts down the seconds from the moment a grenade’s pin is pulled or it is thrown.

New options (in the launcher and in the in-game Recomp Settings, English and Arabic)

• Enemy count (heavy, experimental) — x2 to x5 times the enemies that spawn points create (reinforcements and respawns). Takes effect at the next mission load, can cost frames, and can be turned on or off per difficulty (Recruit, Veteran, Elite, Hero) with four extra switches.
• Stamina bar — a yellow sprint bar above the adrenaline meter that drains while you run; when it is empty you return to walking speed and it refills after a few seconds. Sprint speed, duration and recovery time are options.
• Blood colour — Original / Crimson (the new default) / Dark red / Custom with Hue, Saturation and Brightness rows and a colour square. The on-screen splatters keep their own colour.
• Model detail (level of detail for every model by distance): Game (the original) / Higher / Highest. Higher and Highest draw the better models farther away, so they can cost frames.
• Replaced textures — On/Off while playing, to compare the game’s pictures with yours instantly.
• Dump textures is now Off / PNG / DDS. DDS replacements are read by the port itself (uncompressed 24/32-bit and DXT1/3/5, old or DX10 header).
