Click the images for bigger versions. Note the smooth color gradients and custom textboxes implemented for some of the games. Although these are all running in fullscreen mode, it should be eventually possible to turn on the classic viewframe in most games, if you prefer. The screenshots were taken at a simple 2x internal resolution, but the engine runs happily at any resolution.

The Three Sisters' Story (JAST, 1996)
Status: Completable; graphics need polishing, script needs a lookover, intro script still missing.

Runaway City (Tiare, 1995)
Status: Completable; graphics need polishing, script needs a lookover, intro script still missing.

Season of the Sakura (Tiare, 1996)
Status: Completable; graphics need polishing, script needs a lookover, could use more special effects, intro script still missing.

Angels' Eve Collection (JAST, 1995)
Remakes of some of the earliest eroge made. Not much by way of plot or drama, as you may guess, but fascinating from a historical perspective.
Status: Completable; graphics need polishing, missing special effects.

Angels' Eve Collection 2 (JAST, 1995)
More remakes of JAST's early games; these have a little more plot than the first collection, and the graphics are noticeably nicer.
Status: Completable; graphics need polishing, missing special effects.

Setsujuu ~ Yuganda Kioku (JAST, 1995)
A student goes on a ski resort trip with his childhood friend and a few others. They meet many interesting people while behaving badly.
Status: Completable. Graphics need polishing.

Transfer Student (JAST, 1995)
Don't confuse this with the more colorful localisation by the same name. This is the original version, presented as a proper verb-noun visual novel instead of a daydreaming simulator with an excitement meter.
Status: Probably completable. Ending script missing, graphics need polishing.

Eden no Kaori (JAST, 1996)
A murder mystery at a mansion, starring Joe the private investigator. Much less compulsive verb+nouning than in the earlier games. Some two dozen different suspicious characters, more than one ending.
Status: Not completable, clickable map not implemented yet. Ending script missing, graphics need polishing.

Majokko Paradise (Tiare, 1996)
This is the game I'm maybe most excited over. As far as I can tell, it's like Season of the Sakura but with magical girls. It's set in the same school. You even get some cameos, and the cast performs a song somewhere along.
Status: Probably completable. Intro and ending scripts missing, graphics need polishing, screen scrolling effects missing.

Shyuukan From H (JAST, 1997)
I have no idea what's going on in this game, but it looks funny.
Status: Not completable, clickable map not implemented yet. Intro and ending scripts missing, graphics need polishing.

Tasogare no Kyoukai (Tiare, 1997)
Our protagonist, possibly a student/archeologist/treasure hunter, arrives at a remote village in a quasi-modern setting, and meets the locals. Bad stuff happens, and only you can save the missing girls from a first-person view dungeon! No RPG elements, but yes multiple endings.
Status: Not completable, needs a clickable map as well as a first-person view mode. Ending script missing, graphics need polishing.
In addition to these, there are a few more titles with partial support:
Vanishing Point (Tiare, 1995) is an adventure/JRPG hybrid, allowing you to freely roam around a top-down view of the same town Tiare's other games take place in. Has a great, if short, soundtrack. Needs serious rebalancing to be fun.
DEEP (JAST, 1994) is a point-and-click adventure with first-person combat and a rocking soundtrack. The scripts are similar to the other games, but I can't figure out where the drawing commands come from. Just as well, since the majority of the graphics are ugly digitised photographs (including a few that I can't seem to decompress correctly). The combat is slow, boring and unbalanced. Then again, you can choose to play as one of four characters, who each have unique commentary on everything as you play, and they get different encounters. If the battle system was replaced with a fun minigame, this game could be of interest.
Super Ultra Muttin Puripuri Cyborg Maririn DX (JAST, 1994) is also an adventure with first-person combat, with a decidedly wacky bent. I have the older scripting format only partially worked out.
Tenshitachi no Hohoemi (JAST, 1996) is a dating/raising sim, kind of like True Love, complete with chibi animations, only you already failed at school and instead are tutoring three girls, trying to get their statistics high. The sim interface needs to be understood before it can be re-implemented.
Muchimuchi Sexy Parfait (Tiare, 1998) is already a Windows-native game, with various familiar locations now available in re-colored versions. The engine is very similar to their earlier games, but various argument sizes in the script language have been doubled and there's a new, more colorful graphics format.
Nocturnal Illusions and Mayclub – I can extract the graphics and music from the Windows and PC98 versions, but haven't added script conversion. These are already playable in VileVN though.
