    Here's what I've got:
    Started, but not finished:
    Hardware review (been on the list a loong time)
    Space Invaders driver for FBA
    Chip-8 driver for FBA (needs a revision)
    Not started:
    Re-write/port Neo-Geo CD to FBA
    tool to encrypt/decrypt SMA-protected games
    tool to figure out bitswaps (of any size, data & address)
    R4/M3 firmware patcher (just testing, small fixes left)
    Clean up some FBA additions (Romsave)
    Fix my X-Box & update FBA-XXX pro
    Update/Fix FBA Neo-Geo driver
    MAME Neo-Geo driver to FBA driver converter
    Modify conc.cpp so FBA can use Kawaks/Nebula/MAME cheats.

    I've been working with this girl Kris (Christina) for a few months now, I've been talking with her on a daily basis and we get along pretty well. Honestly, she's not the most physically attractive girl I've ever seen (though she definitely has some attributes I like an awful lot ), but she's got a very nice personality (which IMO is much more important).
    Anyway, a few weeks ago she tells me that she had a dream with me in it (though apparently, it was non-sexual), and I just had a laugh about it. And a week ago she tells me that she's been thinking about me a lot (as in wanting me bad). Now, this is a problem for me because she's got a boyfriend. So I finally talk to her about it, and she pretty much tells me that she's over her bf and she wants to leave him. I tell her to talk to him about it, try to work it out (I'm that kind of guy; plus it makes me look good [you know, being the good guy]), and she has just stewed on it (thought about it) for a week.
    Finally, this week she invites me to a concert, and, of course, I accept (even if I don't get with this girl, she's cool as hell and would be an awesome friend). So a few days go by (this is Monday that she invites me), and she tells me between then and the concert that she'd really like to kiss me. Now, I'm in a predicament at this point, because I'm honestly starting to like her too.
    So she gives me her number and we meet at her friend's house down town so that we don't have to worry about parking. I got there at 7:00, and we sat on her friend's porch and had a few beers (Pabst Blue Ribbon, I think I love you). Then her friend got there and we got inside and smoked some pot (which is unusual for me, I'm pretty reserved and respectable). So finally we got to the concert at the State Theater (in Kalamazoo) to see Keller Williams. At this point I'm pretty stoned and a little buzzed from the beer (don't worry, we walked there). Anyway, we got inside and she's like, "want to get another beer?" So, of course, I got one and so did she (kinda pricey at $4 for a plastic cup full) and we went to the dance floor and started dancing. Every time her ass rubbed against me, I just about had a stroke :S
    Finally, the show ended and we walked back to her friend's house, smoked a little more and chilled. Finally around 11:45, she got up and we walked out. She looked at me, I didn't know what to do, I wanted to kiss her really bad at this point, but she offered a hug, gave me a kiss on the cheek and made me give her one (I wasn't sure that'd be ok ^^), and we went our separate ways.
    Now, I guess this is my problem, should I get involved with this girl? She's got a boyfriend, which I'm not ok with having to deal with, but she wants out of the relationship.
    I guess here are some pros and cons of this girl
    She's smart (has a bachelor's degree in sociology)
    She's opinionated (I like that in a woman, weak women bother me :S)
    She's fun (she's absolutely wild on the dance floor [i'd bet money she's like that in bed too])
    She's funny (I'm constantly laughing when I'm with her)
    She's confident (I love that)
    She's older (24, I'm 22 (so like 1 and 3/4 diff). I don't think that's a big deal, though she is only a few months younger than my older sister)
    She's interesting (she's been a lot of places and done a lot of really cool things)
    She makes me smile (when I'm with her, I can't stop smiling. I seriously smiled for 5 hours straight yesterday [even when I wasn't stoned])
    I find her very attractive (she's not hot by any means, but there are things about the way she looks that make me want to **** her like a horny little monkey.)
    She's kind (she helps out people she doesn't even know and teaches an after school program)
    She's a good friend (I saw the way she treats her friends; Now, I consider myself a good friend, but damn, she makes me seem like an asshole!)
    She's a hippy (I adore hippy chicks for some reason)
    She's got a bf (that she lives with atm)
    She's smokes (pot and cigarettes)
    She claims she's moody (which she seems to be a little, but so am I and so has every other woman I've been with)
    She seems like she's going to be a lot of work (I think she may be worth it :S)
    I donno if anyone will reply to this, but at least I've written down my thoughts, maybe it will help me get this all sorted in my head.

    I started looking at Royal Card (Slovakia, encrypted) on the funworld.c driver in mame. It has a preliminary status due to encryption.
    Basically I started working by comparing it to the non-encrypted Royal Card (Austria, set 1).
    I was able to figure out how half of the bits affect the other bits:

    Dec->Enc 00 -> 22 01 -> 23 02 -> 02 03 -> 03 04 -> 20 05 -> 21 06 -> 00 07 -> 01 08 -> 2a 09 -> 2b 0a -> 0a 0b -> 0b 0c -> 28 0d -> 29 0e -> 08 0f -> 09
    this can be worked out, simply enough, as:

    if (~a & 0x02) b ^= 0x22; if ( a & 0x04) b ^= 0x06;
    I still need to figure out how the first four bits of the opcodes, but this is proving fairly difficult since the encrypted version will not match the non-encrypted version once it has been decrypted.

    So I got bored today and started looking at the pgm2yks.c
    Here's a few lines from the file
    Here's what I got with the algo below
    It's not 100 percent, and it gets worse as you go through the file (0x3c00 values),
    but there are some bits of the decrypted addresses that are correct throughout
    pretty much the whole file, so I'm fairly certain that I'm on the right path.

    unsigned int nret(unsigned int sprite_no) { unsigned int i, a = 0x007c; for (i = 0; i < 32; i++) { if (sprite_no & (1 << i)) { a ^= 0x84 << i; } } return a; }

    Some new CPS-2 games were added last MAME; pretty sweet if you ask me.
    This has also allowed me to almost finish a project I'm working on. I'd like to release soon-ish, but with me, soon-ish could mean a year or two. lol
    On a side note, I just started a new job, so busy busy for a while ^^
