Calypso
Post Posted: Thu Aug 12, 1999 7:24 am
Man, I think that we should all send a collective E-Mail to the author of Calypso for such a fine emulator.
It may not be the fastest of all emulators, but in debugging mode on my computer(P133/32MB), it is actually reasonably speedy.
Plus all of the debugging tools that will come in handy for us all at some time or another.
Man. It's about time someone came up with such a great debugger.
Now if only I understood it all ;)

Man, you could use Calypso on a 286 in debugger mode. A debugger is a debugger. It's not really high
priority. It may take some time to perform a big number of instructions at once (100, 1000) but
it's debugging mode on our crap P133s dosen't really make a huge difference. It's just a debugger.
Now it's emulation, well...That's a whole other ball game there. That shit needs MAD optomization
or something to speed itself up. I don't know what kind of core the guy is using but damn it! That's
like the RockNES for SMS emulators! That's ridiculous for it to be that damn slow! He must program
under a fuckin' PII500 and shit. But, I gotta remember it's a first release and all. Mabye speed will
come with advancement.

This is all too true. I have a book that talks about developing on a 4MHz Z80, and it said that the
user interface is going to spend most of it's time waiting for the user. If a modern-day coder wrote
the interface, however, I feel that it would probably be the other way around. :-)

We can hope so. After all, a p133/32mb (Or is that MiB now?) can run an SMS at full speed using
Marat's Z80 core (I can point to two examples of this, one with source). You just need to do some
very heavy optimizaion in the VDP emulation (tilecache, etc.). Then if you want some extra speed
for some reason (like true fm synth or extra debug info or something), use some ASM. :-)

Hello :)

I´m the author of Calypso, and i´m very surprised by the problem you said. The emulator and the debugger
execute the same function (exec_one_frame_mfz80() (sorry, this but in spanish)). The only difference is that
the display mode is 320*200*256 in emulator and 640*480*256 in debugger, and the debugger calls
a function at the start of exec one instruction.

The emulator have an Allegro bitmap called pemu, and the VDP writes all to this. Then the bitmap is
blitted to the screen. And yes, the blit is FAST in 640 than in 320. I´m very surprised by this, but in fact it is.
I´m working in the new version with a library called Eagle, wich doubles the size of the screen, to work in
640*480 but at a resonably size of emulated screen. If somebody knows the best solution, tell me.

Stay tuned for newer versions. And yes, the VDP engine is TRHEE times slow that the Z80 engine. My
computer is a four years old Pentium 60, nor 450 or 500. The emulator runs at 13, 12 fps.

You don´t kown how to run the emulator? English docs are available at http://www.tel.uva.es/~jdelmen.

Thanks for all.

Saludos

Jose Manuel

PD: feel free to send me ANY question about Calypso.

Eagle is a dream come true. Except you need a faster PC for it. Atleast I do.

Oh. Well, I'll be looking forward to new releases.

Yes. I can read some spanish. It's pretty difficult but I can figure out how to run it and stuff. Words like
byte and bit are universal, ya know?

I make a horrible mistake. The blit speed are better in 320 than in 640. The reason that the debbuguer was
fast is that is has a frameskip of 2 frames. Like the render engine is the poor part of the emulator, the speek
increase considerabily. I saw this looking the code. Sorry :)

And yes, I can spek english at a ridicuosly level. I didn´t pass my June exam of english.

It's a really nice debugger. The only thing I would like is Game Gear support, which the author indicated would be put in at some point in time.

I tried to load the first Game Gear demo that I released and it did nothing. I've seen this a number of times with other emulators.

I would worry about getting the emulator running accurately before wasting time on speed. It's takes a lot longer to fix problems in optimized code.

Yeah. You rock, man!
Does Calypso support sound? (ESS ES1788 AudioDrive)

Ah btw, did you made anything else than the Frog Demo ?

Yeah I made a simple text demo a long time ago. It was the basis of the Neon Spiral Injection stuff.
