0.4.10 is mostly fixes for what players reported after 0.4.9, with a few conveniences added. The HD pack has not changed and is still HD 1.1. Thanks to everyone who sent reports and recordings.
Fixes
- Windows: minimising the window with the settings or the pre-battle page open made the game stop responding.
- Loading the suspend save from the pre-battle page left the page over the map, holding every button.
- A wrong ROM closed the game without a word, like a crash. Every platform now says what is wrong: an archive to extract first, the wrong size, another or a patched game, a missing file. On Android you can choose again; a Steam Deck in Game Mode says where to put rom.z64.
- A line at the 4:3 edges of widescreen battle skies. The fix is in the game, so the HD pack needs no update.
- With 4:3 kept in a wider window, the title’s load menu and other pages sat off to the right.
- Unified weapon upgrades: at a machine swap in a stage opening (フルアーマー百式改 and others), the new machine’s extra weapons started at level 0. They now take the old machine’s level.
- A five-stat upgrade that reached the EW swap dropped the rest of the plan. It now goes on with the new machine, and the unit list says which one it became.
New features
- Return to the title screen: a new entry in the map’s menu and the intermission menu, also on F10, the stage info page and the desktop menu bar; it asks first. The original needed Z+START for this.
- Portable mode (Windows and Linux): create an empty folder named user-data beside Marchwind64.exe (srw64 on Linux) and saves and settings live there, so the whole game folder, ROM included, can move to a USB stick or another PC. The first launch copies in your existing saves and settings; a normal exit syncs them back to the system folder, asking first when the saves differ and backing up the old ones.
- The first launch follows the system language: Simplified Chinese on a Chinese system, Japanese on a Japanese one, English otherwise; from Steam, Steam’s language.
- Desktop menu bar: new Language, Tools and Help menus to switch the language, take a screenshot, toggle 2× speed, open the stage info, load the suspend save or export logs, each entry showing its key.
- Three new cheats (Options → Cheats): real damage, counted past 65535; EXP and money ×2/×5/×10; and an ally morale cap of 150, 200, 300 or 999.
- Pilot pages show kills (not for enemies).
- Chapter title cards in brush lettering: Japanese in a font traced from the original cards and laid out like them; Chinese and English in Ma Shan Zheng.

For problems, Options → Report or Tools → Export Logs in the menu bar exports a problem report. Which Android chips have been tested is on the Android compatibility list.
Download
Get it from the install page or from GitHub. On Android it installs over the old version and keeps your saves; on Windows, extract it over the old folder. The previous changes are in the 0.4.9 notes, and the full feature list in the 0.4.0 release notes.
