weird "xterminator" bug on sms emulation

[nitrofurano]

hi!

when trying to run a homebrew rom (like https://notabug.org/nitrofurano/borielz ... onTheSnake ) i'm getting this from the terminal:

mame smsj -bp ~/.mame/roms -cart1 simonthesnake.sms

Ignoring MAME exception: Unknown slot option 'xterminator' in slot 'slot'
Unknown slot option 'xterminator' in slot 'slot'

usually, since over a decade or more, such error never happened, i have no idea what caused that

mame version is 0.251, from ubuntu repository (recently updated/upgraded, from the current ubuntu version)

this bug is affecting all sms-related consoles, like smsj, sms1, smsbr, smskr, etc.

thanks

This problem appears two-fold.

1. An initial regression where the -cart1 simonthesnake.sms loads but shows nothing - appears to start happening after this commit: https://github.com/mamedev/mame/pull/7377

2. A further regression which causes the confusion with "xterminator" which appears to be a game gear based device. This started, as near as I can determine, with this commit: https://github.com/mamedev/mame/pull/7674

I'll poke someone about this. It might be some simple fixing. Thanks for reporting.

The initial problem occurs when the driver tries to identify special cartridges. In my case, the SG-1000 driver thought my homebrew rom was a codemasters or x-terminator rom.

I'm not sure about the slot part of the error message though. Does it falsely determine it's a special rom and then can't identify it?

SMS cart slot bogusly detect any kind of 0x1000 / 4096 length ROM as x-terminator, which obviously crashes because it's a Game Gear only option. I know it's a thing because Super Magic Drive BIOS also has the exact same phenomenon.
