AGS: Lancelot's Hangover (and others?) - Purple/magenta sprite color appears transparent

[antoniou79]

A lot of the text dialogue in the game is missing. The speech bubbles appear empty instead. However other text in the game is displayed properly.

There's also seems to be a drawing issue (the robes of a guy speaking during the intro are transparent on ScummVM but not when launched from Steam).

This issue ​was first reported on the Android port subforum. However, I was able to verify that it is not Android specific, since I bought the game (on Steam) during the holiday sales and did some testing of my own.

I've tested with ScummVM 2.6.0git (today's build with enable-release from master) and ScummVM 2.5.0 on Windows 10 Pro x64 21H2 build 19044.1415.

These issues are observed during the game's intro, so no need to attach a save game.

I will be attaching ScummVM screenshot(s) and screenshot(s) from running directly via Steam.

Note: The game comes with a content warning. It's humorous from what I understand, but probably not everyone's cup of tea.

Note 2: From ScummVM detection routine (game's language is English):

The game in 'Lancelot's Hangover\' seems to be an unknown game variant.

Please report the following data to the ScummVM team at https://bugs.scummvm.org/ along with the name of the game you tried to add and its version, language, etc.:

Update 18 Feb 2023:

• The game is added to detection, so it's now detected properly.
• The speech bubbles in the intro now contain text.
• The drawing issue with the guy's robes (as shown in attached screenshots) still persists. I think this is the only bug left from the original ones reported.

@antoniou79 may I ask the status of this bug on 2.7.0? Any improvements?
I don't have this game and I can't check...

[antoniou79]

I've just tested with latest HEAD from master (2.8git) and there's been an improvement.

I can see text in the speech bubbles during the intro. I have not compared it yet with the intro when launching the game from Steam again, but I believe that the text would be the same.

The issue with the guy's robes being drawn as "transparent" persists.
