Verifying SimEarth - The Living Planet (1990) (Maxis)

This game is already in the verified section, but just giving it another look since it was added early on.

Checklist

Have adequate installation instructions been provided to match any config files in the DOSZ?
Yes. The config file is needed in the DOSZ because the game can't run without it, and there is no way to create it later.

Have any official patches been applied, if necessary?
No official patches mentioned by PCGamingWiki. This is v1.5 (according to TDC and Digitoxin - original PR said v1.05).

Is the game data in the root of the ZIP (unless game does not work that way)?
Yes.

For games which include CD images, is there a smaller installation variant that offers the same features but needs less files?
Not applicable.

Is the entry in the right variant file (i.e. Freeware)?
Yes.

Have digital versions (Steam, GOG) been checked for matching?
It isn't on GOG/Steam.

Can the game benefit from using embedded data or embedded patches in the datfile?
Yes, I added it to the config file.

Can DoDAT build the game from the install media?
No, some files need to be installed.

If the game requires a yml in the DOSZ, has it been added to the yml folder in the repo?
Not applicable.

Are there .PIF or .ICO or Win32 .EXE files that could be excluded?
No.

Do the file timestamps match the installation media?
No. I added some but not all since the files on the disks are different.

Does the DOSZ run standalone?
Yes.

For CD games, can the game be set up to run without a CD mounted?
Not applicable.

Can the game benefit from using CHDtoOGG?
Not applicable.

Is the game creating a swap file in the .pure.zip that could be avoided by increasing memory size? Or is it creating other bloated files that could be prevented by adding them in the DOSZ?
No.

Does the DOSC contain problematic data (i.e. copyright issue)?
No.

Does the DOSC have copy protection removed, if possible?
This version has no copy protection.

Is the game running at the correct speed? Is CPU year specified?
No CPU setting was specified. I added cpu_year: 1990.

Is the DOSC auto-running and skipping past any obstructions? Is it updated to use WAITMODECHANGE if possible?
Yes, but I updated it to use WAITMODECHANGE.

Does the game have MT-32 support? If so, is it correctly using MT-32 (old) or CM-32L (new), going by the Vogons Wiki?
No.

Does the game have General MIDI support?
No.

Is the game set up to run with the best quality graphics options by default?
It's using 640x480 16-color. There's also a 320x200 256-color option, but the higher resolution seems much better for playing.

For certain old games only - are the graphics/audio improved by specifying video_card: pcjr, tandy, or generic_cga?
Not applicable.

Does the game have a mouse cursor that benefits from enabling input_directmouse?
Yes, I enabled it.

Does a game with separate episodes/executables have the options named and ordered properly in the DOSZ? Do they use the run_utility feature?
Not applicable.

Does the game share saves with a sequel, expansion, etc? If so, is it updated to use the .savename feature?
Not applicable.
