List of worlds with permanent port incompatibility

From MZXWiki
Jump to navigation Jump to search

Due to various issues that would be logistically impossible to fix or not worth the trouble, or due to exploits of certain buggy/limited aspects of MegaZeux, several games have permanent incompatibility with the port. These games will work differently in MegaZeux 2.80+ through no fault of MegaZeux itself but mostly through limit changes, general bad practices, and buggy behavior of old MZX versions.

Affected Worlds

World Category Reason Info
#mzxmzx.mzx Bug Exploit SET RANDOM -32768 32767 Used to cause a crash in DOS versions.
Trashman Dan Limit changes Relies on string char checks being signed Dialog boxes are (even more) broken due to using a negative number as a check against a string char. The port changed string char checks to unsigned, so this trick doesn't work in the port.
Partition Magic Pro: The Game Relies on overflowing a 16-bit counter With the counter size increased to 32-bit, this takes far longer to do.
Hamlet 2 DOS naming conventions Names of files truncated; references in code are in full The Robotic tries loading extended names of char and palette files, but the files are truncated to 8.3. MZX truncates the filename load in DOS to 8.3, but 2.8+ does not, causing the chars and palettes to remain unloaded in one instance. Old copies of Zombie Quest and Hamlet did this too, and with much higher severity, but they have been fixed or repackaged. Another affected game is Halloween, which expects a reference to "halloween.pal" to load the file "HALLOWEE.PAL".
Nova Force Demo 1 Names of files in full; references in code are truncated This game is packaged with cheeseburger.mod and expects to be able to load this with CHEE#DF0.MOD. It's not clear how this SFN was derived, but this shouldn't have worked even in DOS. This mod was removed from the second demo, possibly for this reason.
Technicolor Cheese Wedge Demo Bad Counter Names Counters with leading $ characters are used This game's battle engine uses counters with leading $ characters, including one simply called "$". These are interpreted as strings in the port.
Torn Creation Unspecified Wait 1 issue? "Lack of wait 1s in the scrolling code causes the junk at the top of the boards to be visible when near the top of the board." (clarify?)

Formerly Affected Worlds

The worlds in this section were formerly in the table above but have been fixed in newer MZX versions.

DOS MOD name incompatibility (fixed in 2.92d)
