Mega Man X questions

Deathlike2 · Post by **Deathlike2** » Thu Feb 23, 2006 11:52 pm

I understand there are two versions of this game (well, the US version anyways). ZSNES works better with the 1.1 version (I forget which thread I read for this info). Why is the 1.1 version emulated, and not the 1.0 version?

Is the current emulation of the chip just a hack, or actual emulation?

Occasionally, the powerups dropped by enemies disappear when it hits the ground. It occurs more often on the 1.0 version and sometimes on the 1.1 version. Is that a symptom of incomplete emulation/hack of the chip or is it incomplete emulation of the game?

Wasn't 1.0 the one with the copy protection stuff on it?

There is no chip.

Improper mirroring.

the chip you speak of is only in megaman x 2 and 3 not megaman x 1.

Deathlike did, actually.

If I recall, BOTH versions of Megaman X have copy protection, but ZSNES has a hack for 1.1.
I could be wrong.

I'm not mixed up with the chips.. I already know Mega Man X don't use the same chips that Mega Man X2+X3 use.... I should've called it copy protection.. or whatever it is.

its nothing to do with copy protection... thats just a side effect of what it does... its an extra processor i think. (built into the game cartridge/console)

Megaman X1 has a copy protection where it mirriors rom data into some kind of memory. This is cause X1 has no sram, so when you try to play it on a copier(which has built in sram) the copy protection stops the game from working. Something like that.

Had a hack. Each one has a different kind of mirroring check. We pass one but not the other.

Once in a while, the hack doesn't work... though it comes and goes (it's infrequent and very random)

I just said had a hack. The hack we had did work. We no longer have a hack.

Well, I'm not aware when this hack was removed. I'm only saying that the last time I've extensively played Mega Man X, the emulation of the mirroring check did randomly fail. I guess that was before the hack was removed.

So Megaman X (1.0) is not a good copy to have

is there any more games like this that ZSNES needs 1.1 and not 1.0

franpa · Post by **franpa** » Mon Mar 13, 2006 7:17 am

general rule of thumb... always use the latest version of roms unless you want to use cheats and cheats only work on a specific version of rom.

also pal isnt fully supported yet so basically only like 2% of all pal games will work without issues.

they had copy protection on the SNES? i can't imagine how people would try to mod their console to play a pirated game lol.

speaking of which, anyone hear of that site that featured a german product that rewrote the SNES cartridge so you could transfer roms back onto the cartridge? I remember it did something like erase the EEPROM. So basically you could patch a game and play it on the console

What you speak of is known here, it is the site of a German guy who modified SNES cartriges by writing data onto eproms and replacing the original ones on the cart. He used old Illusion Of Time/Illusion Of Gaia carts. That way he made a German Seiken Densetsu 3 cart, German Bahamut Lagoon, German Final Fantasy VI, English Rockman & Forte and so on. You can find it here:

Makes me want to reflash my Lufia 2 cart with my patched up one to fix all the crap they didn't clean up.

The SNES console itself did not have built-in copy protection. A handful of games had innovative copy protection.

The same backup devices that allow you to copy ROM data to a PC also have internal memory that allows you to load games and play them on the real console. These devices allowed people to play copied games before there were emulators for any console.

I've been using my N64 devices to play games that have never run correctly on emulators.

Capcom figured out a way for the game software to determine whether-or-not it's running on a backup device by checking for SRAM save memory, which that particular game is not supposed to have inside the cart. Because backup devices were designed to allow you to play any game (including those with SRAM), the SRAM is detected by Megaman X and the game exhibits intentional problems that make it difficult or impossible to

The actually did SNES require a special chip to be present in each cartridge. Backup devices got around this requirement by allowing you to insert any cartridge, which has pass-thru connections so that the internal chip is read by the SNES. When this was engineered, it was really meant as a way to prevent companies from selling SNES-compatible games that were not licensed through Nintendo. I've only seen one unlicensed SNES game, and it required a piggy-back cartridge on the top.
