Here I'll list bugs I find in the games I own and play, since I'm a weirdo collector, most of them are shit from far east countries. Since most of you totally ignore and don't care about these games and they are not widespread, I decided to not open a topic for every title and created this niche. Pm me for any info or help.

Bear hero: glitch with energy bar (garbage + energy not visualized).
Link to video showing the bug.

Rockman 123 (taiwan): color palette is more vivid compared to the game without dgvoodoo2, this is weird, this doesn't happen in all my pcs.
Bug: In this game clicking on a specific image allows the player to start the corresponding game, if you force higher res, the mouse cannot move freely in all the screen so choosing the correct game is hard. (game debug log here).

Yulhyul Kangho: color palette is wrong, it looks and feels like an ega 16 color crap.

Bust a move 4 / Pubble Bobble 4: bad performance, raising rendering resolution makes things even worse.

Rc de go: it hangs with a black window.

Tonko4: Game frequently crashes when returning to game from save menu (you can reach it during gameplay, it's a button-like thing on floor). Main menu items wrong color, it's impossible to understand which one is selected. Weird ingame graphics, tonko and enemies have some weird metal effect on textures.

Asuka 120% burning fest return: it crashes on startup.

Suchi pai 3: You can hear sound but it automatically switches back to desktop (with game active and running in the taskbar, clicking on it does nothing)

Nba powerdunkers: This thing is really broken. Good luck running this.

Are there playable demos of those games that I could download from somewhere?

I only found Rockman 123 so far. The cursor issue is indeed present for that game but I didn't experience palette problems (Win10 FCU). Oh, and intro video doesn't show up for me, must be some codec problem.
(About the cursor issue: the real hw cursor is locked into a subrect of the screen, but the logical cursor doesn't appear for some reason. The opposite of what is expected. Game is selectable in this way, altough not easy.)

It's a pure software rendered game so forcing resolution makes no sense here. Use pixel-multiplied output instead to avoid blurry appearance (ImageScaleFactor in the INI file).
Performance is bad indeed, but fast video memory access helped for me a lot if not abolished the problem.

Nichibutsu mahjong collection: it crashes on startup.

Shadow of memories: well...this is a long story: this game was originally protected by securom v4, new OSes support such disc based protections no more. An existing hacked exe removes protection AND makes the game Win7-8-10 compatible. It runs correctly without dgvoodoo2 but if you put the usual dgvoodoo2 files in the game directory, it crashes on startup.

Zero Comico: (with fixed japotek3d.dll), compared to vanilla video card, it lacks loading screen images in dgvoodoo2 (black screen).

Zero Comico and Shadow of Memories are fixed.

Nichibutsu mahjong collection: well, it has a really poor coding that is completely incompatible with modern DX. The game runs on multiple threads without pumping its message queue in the main thread.
So, the game runs into a deadlock right after starting it. The only chance is to run it in forced windowed mode (I made some fixes for that) but its palette is still wrong (natively too).

I didn't notice that. I start it by nbgame.exe, and then I select the game. Without dgvoodoo2 dlls, if I use this method it works with proper palette (only problem I found is garbled nichibutsu logo video).
If I directly use gion.exe or hats.exe it hangs with a black window, in every case (dgvoodoo2 or not).

Thanks for keep fixing games 😀

Considering it's a korean production (I collect these things for preservation and passion) I wouldn't be surprised if it wasn't stable on vintage hardware too!

I tried latest 2.63.2 and I really appreciate that now Idol Janshi Suchie Pai 3 main menu screen doesn't go background. Still not perfect but at least it's playable.
Now I'm boosted to test if other games are fixed.

Also, any fixed exe also switches the subtitles to English. Even if the original exe used French subtitles and UI all the way (French PC release). Other locals should have the same problem.

The resource/data files are the same. So it seems the behavior is embedded in the executable. I would love to fix that, but I'm not that good with OllyDbg...
