v0.3.9: Fixed some large games inside multi-game containers launched from the library crashing after 2–4 minutes of play: the container couldn't read the game's recorded address-space needs and reserved only 3 GB, so it ran out and crashed; it now reserves space based on the game's own record (or its own layout needs if it hasn't been played yet), and 4 more fixes

Fixed some large games inside multi-game containers launched from the library crashing after 2–4 minutes of play: the container couldn't read the game's recorded address-space needs and reserved only 3 GB, so it ran out and crashed; it now reserves space based on the game's own record (or its own layout needs if it hasn't been played yet). Further fixed "phone is plugged in but not recognized": if the computer can see the phone, it now just installs instead of blocking in advance based on pairing / online / Developer Mode status; if the install really fails, the system's reason and next step are shown. Fixed Windows self-sign exports failing at step 4 "Write install notes" with permission_denied after several GB had already been written: if the old export folder is held by Explorer, the self-sign tool or antivirus, it now waits and retries; if that still fails it writes to a new time-stamped folder, succeeds as usual and tells you the new location. If the resource pack has no shader library (for example when the game.img from the resource pack folder was copied in directly), the game no longer stops at "Game files are missing" on launch: it plays as usual and compiles shaders the first time they're needed, which may stutter for the first few minutes. Several actions are no longer blocked in advance: deleting a game from the phone works even if this computer has no record of it (installed from another computer); on Windows a missing bundle ID is derived from the current account; choosing a whole drive or your home folder as the storage location now creates an S2Arm folder inside it; importing an update is no longer rejected by version number up front — the content is checked after unpacking and you're only told if it's really wrong.

What changed

Fixed some large games inside multi-game containers launched from the library crashing after 2–4 minutes of play: the container couldn't read the game's recorded address-space needs and reserved only 3 GB, so it ran out and crashed; it now reserves space based on the game's own record (or its own layout needs if it hasn't been played yet).
Further fixed "phone is plugged in but not recognized": if the computer can see the phone, it now just installs instead of blocking in advance based on pairing / online / Developer Mode status; if the install really fails, the system's reason and next step are shown. An occasionally empty device list is re-read automatically, and the Mac launcher no longer pops up "can't read connected devices" when a refresh is cancelled.
Fixed Windows self-sign exports failing at step 4 "Write install notes" with permission_denied after several GB had already been written: if the old export folder is held by Explorer, the self-sign tool or antivirus, it now waits and retries; if that still fails it writes to a new time-stamped folder, succeeds as usual and tells you the new location. The "next step" for permission errors on Windows now gives Windows instructions.
If the resource pack has no shader library (for example when the game.img from the resource pack folder was copied in directly), the game no longer stops at "Game files are missing" on launch: it plays as usual and compiles shaders the first time they're needed, which may stutter for the first few minutes.
Several actions are no longer blocked in advance: deleting a game from the phone works even if this computer has no record of it (installed from another computer); on Windows a missing bundle ID is derived from the current account; choosing a whole drive or your home folder as the storage location now creates an S2Arm folder inside it; importing an update is no longer rejected by version number up front — the content is checked after unpacking and you're only told if it's really wrong.
