Puzzlum : Realm of Existence net-game for NES

[jargon]

hi.

i am planning on combining patches versions of Mystic Quest and Arcana.

obviously Mystic Quest will be backwards ports to NES.

if i can't backwards port Mystic Quest to NES, i will either have to foreward port Arcana to SNES, or else combine the patched Mystic Quest ROM with a patched Eye of the Beholder ROM image instead.

i intend to make the original game on NES tho.

so if it is possible to backwards recompile MQ for NES please let me know, as it just dawned on me MQ is a frickin SNES game!

i originally planned on combining the MQ engine with the Eye of the Beholder engine, but found out EotB never existed for NES.

now i am double stuck.

Arcana is the closest NES engine i can find to the Eye of the Beholder engine.

What can i do to backwards port the SNES Mystic Quest to NES?

or is there a game that already exists for NES that is virtually identical in engine style to MQ?

much thanks.

You might as well write your own game from scratch, because there's no way in hell you're "backwards porting" an SNES game to the NES without the source code (and even then, it'd take a herculean amount of effort). Here's just a few of the problems you'd encounter:

- converting 16-bit code to 8-bit
- rewriting the sound engine
- rewriting the graphics routines
- rewriting the control routines (the SNES has 4 more buttons than the NES)
- bankswitching (the NES can only access 32KB of ROM at a time)

Also, the idea of "combining ROMs" is laughable, even if their engines seem similar. Do you honestly have any idea what you're talking about?

wow!

Please read a book on 6502 ASM. BTW, you don't 'compile' NES games, you assemble them. Compiling refers to taking a high-level language, pulling small chunks & bits of pre-written code & putting it in the order of an executable program. Or at least a process similar; I never really looked too much into how the whole compiling process works...

Assembly, on the other hand, is barely a step above binary. You have to know the CPU's entire instruction set, how each instruction functions, &, hell, if you're an audiophile or someone who likes to write during vblank, you have to count cycles!

I myself have put months of off-time (maybe about a couple hours a week) into learning 6502 ASM & creating a small lightgun techdemo. Currently all it does is scroll & blink. The point being, you can't just comment out a few lines, change a few variables & pop out a game on the NES. It takes ALOT of time & patience...

I thought Arcana was already a Super NES game.

This is one of the messages that make less sense I've ever read. Combine two game isn't possible, unlike what the alchemy pot can do to items in Dragon Quest VIII.

I highly doubt that's what this guy has in mind.

Shame on you tepples. That's not combining two games now is it.

Then what is?

[Dwedit]

This is!

[atari2600a]

All-Stars is more of a multi-cart remake, w/ SMW if you got the bundled version...

This is! [Metroid clone starring Mega Man]

Which is why I'm disappointed that Nintendo isn't doing a "Capcom Vs. Smash Bros." type game.

Perhaps you can do something with MUGEN...
