Problem with Sunsetriders game

I use ssriders parent rom non merged for mame 0.273 and at some point during the intro or during the game a transparent line looks like a wave similar to a scanline runs across the screen from bottom to top of the screen

With some configuration in the emulator, is it possible to adjust this bug?

I tried a print but it didn't appear in the print

When you start the game/system, you should have gotten this big bad warning box stating that there are known problems with this system, namely that the graphics are not perfectly emulated. There is nothing you can do about this, you will just have to patiently wait until a developer decides to look into the issue.

1) Do the clone versions of ssriders also have the same bug?

2) these emulation errors are errors in the emulation within the emulator or also ROM errors? Is it possible to use a MAME 0.273 ROM non merged in a future version of MAME in the future and obtain perfect emulation of the game with old rom and new mame?

Have you tried to see if this is so ? Hint: You will see the same error box when you start the system/game.

As far as I can tell, at this point in time it is believed that the roms are good dumps, and the imperfection lies in the emulation of the system. If in the future discoveries are made to contradict that, this will be updated to reflect the knowledge at that future point in time.

yes I saw this message when opening the game


Do the other clone versions of ssriders also have the same bug?

The hardest thing about mame is that when you update the emulator, you need to change the fullset to the emulator version. If all the current non-merged or merged roms (Mame 0.273 or 274) are already 100% dumped with good and complete dumps, it would be great if you just update the emulator to take advantage of the improvements.

Also, this is not entirely true (as I interpret your statement). When updating the emulator, you only need to get/update roms which have changed from the previous version (re-dumped) or added (new games/systems), and not again 'all of the roms that mame supports'. (your 'fullset').

If the ROMs continue to be reduced, it means that good emulation still depends on modifications to the ROMs and not only on improving the emulation within the emulator.

Is it possible to use a non-merged MAME 0.273 ROM on a MAME 2000 or MAME 2003 emulator? Many emulation devices, TV boxes, smartphones, laptops, retroarch etc. use only these two versions of MAME.

Yes, that is exactly correct. You need a good dump of the roms, as well as good emulation of the hardware. If it is discovered that a specific rom dump turns out to be incorrect, it would be preferred if it could be replaced by a better/correct rom dump in the future. And if the emulation of the hardware turns out to be imperfect, it would be preferred if it could be corrected and updated in a new version of the emulator.

You need to use the rom versions that correspond to the mame version used.

The mame (rom) versions 2000/2003 you mention, are roughly 25/22 years outdated by now. You cannot realistically expect things that old to work correctly with the current mame version (or a 25 year old mame emulator to work with current 2025 roms). The 2000/2003 rom versions are only still used by heavily outdated and/or severely hacked-up mame emulator versions (like, but not limited to, retroarch). You are far better off using the latest mame version, and the rom versions that go along with that.

Do the clone versions of ssriders also have the same bug?

Another error I noticed in the games Mortal Kombat 2, 3, Ultimate 3, WWF Wrestlemania, and NBA Jam is that the sound is very low compared to other games.

When the graphical errors in ssriders are fixed, will the ROM also be changed or will only the emulator be improved?
