  1. No. Games that were manufactured in significant quantity used mask roms. They'll probably outlast the cockroaches. Small quantity runs - like homebrew, pirate carts, and prototypes - would use proms.
  2. Well, I assert that the law itself is silly. I did mention that it flew in the face of common sense, right? Anyway, I managed to track down some case law that hinged on 117(1). (mostly lifted from from this pdf) In Micro-Sparc, Inc. v. Amtype Corp., the court pretty much nullified the whole authorizing of copies text in 117(1) by making it impractical... Micro-Spark published Nibble Magazine. Nibble had programs the users could type-in, and for an additional fee they would also sell the users a diskette with the programs on it. Amtype offered to sell the magazine-purchasers a "type-in" service, in which they'd sell the magazine purchasers a diskette with the programs for less than Nibble was charging. The court ruled that the sole purpose of 117(1) was to authorize the owners to input computer programs into computers. (!) The court then reasoned that section 117 did not permit subscribers to authorize Amtype to prepare diskette copies for them, because Amtype did not itself input the copies into the subscribers' computers. Instead, the subscriber used the dis­kette to input the computer program into the computer. So Amtype made backups, no doubt, but because they didn't make backups on the user's computers, they weren't exempt under 117. Besides the fact that the case makes authorized backups under 117 impractical, it also illustrates nicely that the source of the bytes (however identical to the end result) is critical when considering a case. To quote Dickens, "the law is an ass."
  3. Sure, I was paraphrasing. The difference is not the crux of my disagreement with your interpretation of the exemption. I say "of that computer program" means the item that you purchased and have in your possession. Your interpretation of "of that computer program" (as I understand it) is the program code, or any implementation of that computer program. I say that's overreaching. While admittedly they are a biased source, copyright.gov seems to agree with my interpretation. Another supporting view here: https://security.usf.edu/copyright/copyrightsoftware.php
  4. The courts don't get hung up on technicalities. It's why you see stuff like "reasonable man tests" and the like applied to words that have ambiguity. As far as case law, in Atari v. JS&A the court ruled that rom/cartridge backups were not covered by section 17 USC 117(a)(2).
  5. jrok's solution still works for what you want if you just add an extra jump in there. I think it's the cleanest you'll get using pure bB... rem off-the-cuff pseudocode... rem No map-edge boundary checks in this code... rem Need to add some in if the player isn't prevented from moving up at the top of the map, etc. if player0x=16 then screen=screen-1 : player0x=140 : gosub screenchange if player0x=141 then screen=screen+1 : player0x=17 : gosub screenchange if player0y=20 then screen=screen-5 : player0y=80 : gosub screenchange if player0y=81 then screen=screen+5 : player0y=21 : gosub screenchange rem ...game flow continues... rem elsewhere, out of the main code flow... screenchange on screen goto screen1, screen2, screen3, screen4, screen5, screen6, screen7, screen8, screen9, ..., screen25 screen1 playfield: XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX X............................... X............................... X............................... X............................... X............................... X............................... X............................... X............................... X............................... X............................... end return screen2 playfield: ...etc. ...with assembly you could have your own playfield loader and a table of pointers to the rom containing each screens' playfield data. But I think the solution above is clean enough.
  6. My condolences. Sad, but it can happen to old proms.
  7. pray its not bitrot clean the contacts clean the switch inspect for mechanical damage or cold joints with a multimeter, check the switch, the capacitor (should read open), and other components. Good luck!
  8. Just started playing it tonight, but I had a really good time with it! So much so that I came on the forums to post about it and found your topic. The gameplay is very similar Punch-Out, only with more varied enemies and the ability to upgrade your gladiator's attacks, defenses, and magic. Similar sense of humour too! If you didn't enjoy Punch-Out, its probably best to steer clear of Rage. If you like Punch-Out, I think you'll enjoy Rage of the Gladiator just as much, if not even more.
  9. I've read the act many times. There's no exemption for making a copy of someone else's copy - to the contrary, the exemption states that you must be the lawful owner of the copy to make an additional copy. The man in the robes may buy your defense of owning another lawful copy as well, or he may not. If he follows the letter of the law, he won't.
  10. Agreed, but with the provision that the media is perishable - as far as case law goes. It doesn't need to. Copyright law states that no copy is allowed without permission of the holder, except for the stated exemptions. So what isn't expressly allowed is forbidden. You have no stated legal right to someone else's copy, even if you own identical media. No matter how much it may fly in the face of common sense. No case law here AFAIK, but for what it's worth (not a whole lot) copyright.gov agrees with me on the point.
  11. The Mame authors just decided to inform you that you should use the emulator with legally obtained roms. They aren't required to do that. Other emulator authors decided they didn't want to have similar notices.
  12. I think Randy was being used as an adjective, not a name. Later in the article they attribute a quote to her using the name Amanda. While the cheese factor is high, it does seem a bit late for an April Fool's Day article.
  13. Its a single case. She fell from the Wii Fit board and damaged a nerve, which made her hypersexual. No real chance of it happening again, unless Nintendo's R&D can replicate it.
  14. From the Daily Star: A woman has gone from Nintendo to nympho after a fall from her Wii Fit board turned her into a sex addict... Seems to me it was her clumsiness that caused it, rather than the Wii Fit board. Still, I expect we'll see husbands lining up for Wii Fit boards soon.
  15. Yes, that's covered under fair-use. Specifically it's a backup copy, though I suppose it could also be considered format-shifting. Either way, both have been recognized as valid fair-use defences. To qualify to the letter of the law, you'd need to download/transfer the roms from your licensed media, rather than some rom site.
  16. Right. Robby Roto and Gridlee are roms that have been placed into the public domain, so they're legal to download and play. I thought Poly Play was in the same boat, but it appears it fell into an "unenforceable" status rather than being put into the public domain.
  17. Try Philsan's L.E.M Lunar Excursion Module homebrew. It's a fun little Lunar Lander type game!
  18. Nobody here has said that emulating games is illegal. Only that copying roms, or using copied roms, is illegal unless your usage fits the copyright law fair-use exemptions. I'm sure a lot of the developers use MAME to enjoy their works. Unfortunately, for the most part, they don't own their games. They're owned by large corporations. If someone thinks there's a buck to be made by legal action, it will happen. If they don't think there's money to be made, you'll be safe. But that doesn't alter the legal status of copying their roms one bit. If the copyright owners of roms support emulation, they should place their roms in the public domain, like Robby Roto, Gridlee, and Poly Play. Not holding my breath for it.
  19. Yup, the busy-wait timing method definitely appears to be a work-around.
  20. Encountered on the same platform, but not corrected. Building from Ubuntu sources doesn't help. [edit - nor does building from the 3.0 sourceforge sources.] It seems if you hit escape right after launching, the bug isn't triggered. Also, if you wait long enough it does eventually work and go back to the menu, but I'm impatient and usually do a "killall -9 stella"
  21. Mechanic: Somebody set up us the scissors. Operator: Main screen turn on. CATS: All your panda pencil are belong to us.
  22. Yup. As you noted it will make the lines wider, so it all depends on how much accuracy he's going for.
  23. Maybe go for a euphemism instead, like "quest for the missing member" or "quest for the severed unit".
  24. In the US the copyrights will expire 95 years from the publication date, assuming there isn't another copyright extension law passed. And it's extremely likely there will be another copyright extension law purchased by Disney and Co. by then, so it's probably most accurate to say "copyrights will last forever." Actually, reselling artistic works isn't illegal. Not yet, anyway. I agree with the general sentiment here that it's probably safe to enjoy Mame in one's home, even if you're violating copyright laws to obtain the roms. But I detest the laws that make criminals of us as we enjoy our hobby, and I worry about a day when organizations like the ESA may decide it's worth their while to turn their lawers on those that support retro gaming. They may do it just for settlement money, similar to how the RIAA has operated.
  25. Its a simple matter of copyright law. Unless you have obtained the right to use the rom dumps from the copyright holder (either by the copyright holder selling you a copy of them, putting them in the public domain, etc.), you're breaking copyright laws. Your friend may feel he has a moral right. But that's an entirely different point as to whether its illegal or not.
