Vmu Emulator

[finty]

Ok, just like kknd_cf I have just started to learn to program, it is going to be a summer project.

But if I get good enough I might try and port one of the VMU emulators (probably this one). Do you guys think this would be a good project, Im not suggesting doing it as a first project but deffinitly somewhere down the line.

Also is this deffinatly viable? Does anyone have the specs of the VMU?

The VMS/VMU is only a Hitachi 88K, if you can't emulate that on the ARM9 we may be in bigger trouble than we had previously thought.

I know there are a couple open-source UNIX VMS/VMU emulators; if they use SDL or something it should be trivial to port them over.

It seems like a great project, just because it dousnt seem like the most difficult thing to do. The downside is theres nothing really worth playing on it...

I know it wont be hard, But as a project just for learning it should be good fun.

As for the game thing, there are guides on the internet for making your own, but most games are kind of crap. There is a couple of Tamagotchi clones though

EDIT: Does anyone have the full secs of the VMU? I know the port is possible, but I would like the full specs and im in school and most sites are barred

VMU specs:

* CPU 8-bit
* Memory 128 KB
* Display 48 dot (W) x 32 dot (H) Monochrome
* Display size 37 mm (W) x 26 mm (H)
* Case dimensions 47 mm (W) x 80 mm (H) x 16 mm (D)
* Power source 2 x button batteries, w. auto-off function
* Sound 1-channel PWM sound source

thats all i could find.....but this might help some.

This site has everything you'll ever need to know to work with Dreamcast hardware or VMU.

Hm, I could swear the site used to say the VMS/VMU used a Hitachi 88K, but it looks like it's a Sanyo 86K-compatible something or other.

Ok thanks guys. Hopefully by the end of the summer I will have enough knowledge to do this

I tried porting the VMU a long time ago using one of the open-source VMU emulators with Unix and MSDOS source code, but they relied on time.h for their timers and initializing the VMU memory. Not to mention the source code had 1 comment in it, which was "???".

 

[finty]

Does this mean that it wont be possible?

 

[generalnmx]

Nah, just because I got frustrated doesn't mean it can't be done. I'm sure someone like yoyofr, rlyeh, or ThunderZ could sneeze and out flies a VMU emulator.
