I am finally beginning my project. My project is going to be over a great deal of time I feel and as such, I am taking baby steps with it. At the moment, I working to get the software "down pat."
I will be transferring everything to a newer, more powerful computer, but until I put the order out, I working with ROMS and maLa on a sapre system I have at home. So I guess, onto the questions.
I found ROMcenter last night and all i can say is WOW!! (please let me know if there is something better). Unfortunately, there isn't a good help or tutorial for how to use it and I am still very new to the structure of ROMs and how they work. That being said, I installed it and started playing around last night.
I have a rather larger collection of ROMs at the moment. Although it would be awesome to have an arcade cabinet with 5000 games on it, it's not very friendly when you want to play something. Plus, I really don't care for oversea games. So i started working with a select group of ROMs to get used to ROMcenter. My questions are this...
1. for the split, merge, etc. options, there is an option for one game per set (1G1R - i believe)....i checked this assuming it meant that instead of having multiple rom sets for a single game you have just one...i.e. instead of maintain a main game, then ver 1.2, ver 1.3, etc...you just have the main game...is that the correct interpretation??? if so, does rom center just utilize the latest working build???
2. is it safe to trust ROMcenter for the roms it marks as red - meaning can't be played...for space reasons, i will likely just ditch these roms....i just don't want to have to check each rom...i want to know i can trust the software....
3. the greyed out roms...this is where i am very confused....it seems that multiple roms are grouped as sets....i have a "main" rom that is green and playable and at least one "greyed" rom that isn't playable but has a couple of files in it....are these greyed files a result of the one game option...meaning that these were just versions of the main game??? if so....is it same to delete these 'greyed' roms...or will this bite me later on possibly other roms?
non-ROMcenter related
the xml file generated by Mame listing all the roms, i am assuming that is all the roms that mame has been programmed for to archive and which ones they are working on correct...meaning if you don't find a game on that list, it has not yet been archived for use with mame correct?
finally....last but not least...organization....
once i get all the roms sorted out, non-working and whatnot.....i want to sort them out into groups....i would like to have a list like fighters, platformers, etc....and i would also like to separate out lightgun games and racing as i won't have a wheel or lightgun...yet

.....i would also like to group by year if possible....what is the best software to do this....i have downloaded Romlister but haven'd played with it much yet....does it integrate well with maLa...(it appears to)....
in maLa is it possible to have a rom belong to multiple categories and have them all listed in MaLa??? like have fighting games as a category to which SFII belongs...but also a 90's category that also includes SFII??? and to enable categories like this in MaLa is just about changing to the tree structure??
thanks so much guys for all your help....i promise to give back...i am a fairlly competent computer and tech guy so the software isn't the problem, i am just trying to decrease the learning curve if possible and learn what is the best software for managing all the data...
thanks again...
