Hello all!

Being very new to emulator programming, I would like to ask a couple of questions.

1) Is there a z80 emulator library for the ARM CPU?
2) can anyone give me any other help/advice for Bomjack or emulaotr programming in general?


Cheers!
 
In addition, the Mame port runs a few Z80 games at the moment. Doesn't run very much at the moment, and doesn't even try Bomb Jack (mores the pity :D ), but it's only had one release.

If you want to _play_ BombJack urgently, then the ST version is probably the best. It is out there (but can't say where).
 
bombjack on the st is okay but I:

a) Want the real thing
and B) have allways wanted to implement my own emulator.

Saying 'b' though if someone beats me to it then i won't bother...
 
As a fan of the ZX Spectrum I'd like to point out that its Bomb Jack version is pretty good :)

And there is a good Speccy emulator.

yes, there's a asm z80 emu already


do you mean the one in the SMS emulator? If so it's a bit wrapped up in the emulator itself

I was referring to the one that was offered to you for your Gigadrive, but I don't know whether it's public domain, or only available to certain people. Hence the reason I didn't drop a link. Don't know if it belongs to SMS or not.
 
Well, I don't know about it being a "Mighty" Bombjack (doesn't state it on the title screen and there's no Mighty Bomb Jack on Mame), but it is definitely different. Bomb Jack arcade was a vertical screened game, and the ST version is a horizontal, which means the two are quite different. Whether the ST's is any better or worse than any other computer versions I couldn't say - it's the only version I've checked out, but it isn't bad; admittedly not as good as the arcade, and naturally not as good as Bombjack Twin.
 
Bomb Jack is one of my favorite games and I started playing it with the Spectrum, then on MAME (I never actually played it on an arcade before).
Even though the graphics are "speccy" and there is no music I believe that the Spectrum is the best conversion of all because of its gameplay.
There is one for the SG-1000 which is a joke. And pretty much all other systems that I saw conversions for had always a problem with the gameplay.

One conversion that was actually pretty decent was "Bomb Jake" for the Palm system. But that one had shady copyright and disappeared from the web after a while.

EDIT: more info on the Spectrum conversion here.
 
Would be nice to have the original arcade version of BombJack on the GP32. The original sound also would be a bonus.

Yes it combined into a SMS emulator. Not that this is in itself a bad thing, it could be extracted, it's probably just a bit of hassle (especially if you don't know much about the code :)

At the moment I'm planning to fiddle around with DAZE again at some point. If nothing else, it wouldn't hurt to have two ARM z80 cores.

The MAME z80 core is very good (fast & accurate). And yes, the Spectrum version of Bomb Jack is not bad at all. Well worth the try !

I'd disagree there ever-so-slighty - the MAME core is accurate, portable, but I don't think it could be described as fast - or at least not in the grand scale of things. It is fast in the sense that for a C core is it probably very very fast, but for example if you compare the MAME core to RAZE, Doze and MZ80 it's probably about 3-4 times as slow. However that it the price of being portable.
