OK. Let me think.
Your card is a 4554, correct? Google is not helping me identify it. Is that a mobility card (in a laptop or similar) or special card of some kind, maybe a firepro workstation card, or a regular desktop card? If it's a mobility card, it's really a rebadged 3000 series card, and will probably be running up against the dot-clock limit. Older mobility cards are not expressly supported, but normally the chipsets they're based on are, so they still work a lot of the time.
I don't think you actually want to do get modes from the XML anymore. Did you follow the crt_emudriver 2.0 guide for the 4000-series-and-older cards? This one -
http://geedorah.com/eiusdemmodi/forum/viewtopic.php?id=298If that card is a non-desktop or mobility card, try setting your minimum dot clock to 8 in VMM (and possibly in mame.ini). This means you get 640x240p, and you have to adjust your emulators to suit. A 3000 series card can't handle 320x240p as that mode only has a dot clock of about 7.5(MHz). Even better is to go all the way through the guide and install super resolutions (like 2560x240p). (if needed, you can find recap's guide to installing GM on the crt_emudriver guide forum, follow it AFTER calamity's install guide, but don't use cleanstretch for newer GM builds, just set resolution to 2560x0 and the super resolution trigger to 2560 - these are in the core switchres options section of the mame.ini file that he talks about.)
If that IS a desktop 4000-series card, or none of this works, start over. Fresh windows install if you can, otherwise removing crt_emudriver might be good enough. Then follow calamity's guide only, do not adjust the dot clock.
(The EDID emulation option is there in VMM, but possibly greyed out. Take a look at the guide for the 5000 series and up cards as well, if you like, remembering that for your card you DON'T want to enable EDID emulation.)
(The generic_15 option in the guides is the monitor range preset. You set this, but the preset info in in monitor.ini. Read it, and then read the monitor range sitcky at the top of the GM forum to understand it. Once you've tried all the advice above, try setting your preset to arcade_15 for an arcade monitor or PVM to get wider ranges and more or better-suited modelines)
