Emulateur Game Boy déjà pour Casio Prizm fx-CG/Graph 90+E !

With Super Mario Land 2 8 golden coins, I'm also getting strange things on the Graph 90+E
(you may consider it's the same as an fx-CG50)
.

After just some steps, before reaching the first blocks, I automatically get the head-wings.
If I jump now, I'm flying up through the top of the sky background, and end up on the top a white background.
I can then fly to the left or to the right, but I can't see anything as I suppose I'm stuck at the top of the level 1 map.

It's very strange, it's as if most Game Boy CPU instructions were working, or I would have gotten garbage, an early freeze / nothing, or a crash... but some CPU instructions were failing.


All files were sent from my CG20 on which they are working to my Graph 90+E.
We can suppose the data transfer is not working properly for some reason between these 2 models, and is storing corrupted files, which could explain why CGDoom complains about a missing doom.wad file.

I'll try again as soon as possible by retransferring the same files, but using the computer this time.

Ok, sorry. I've retransferred both ROMs and the emulator from the computer.
Super Mario Land 2 and Zelda Link's awakening now seem to work perfectly. :)

So either the 3.00 OS version I have has a faulty calculator link code...
Either they did slightly change the protocol, and the Graph 90+E / fx-CG50 doesn't communicate properly with older models.


But CGDoom is still complaining about a missing doom.wad file though...
Going to try again, after all, it was working in the emulator...

No, CGDoom doesn't want to work, still complaining about not being able to open "doom.wad" file.
I did even tranfer both files back to the computer, they're identical.

So the link functionnality does't seem to be the problem this time.

:D That's awesome! Glad it works out of the box.

The overclocking code is probably not even necessary, I will look into detecting the new calculator so that it does not show the option.

Ah, I'm very sorry...
It doesn't seem to be related to the link, it seems to be random...
And random bugs are the worse...

I've just launched Zelda another time, I didn't retransfer the files, and this time I'm getting the beach-freeze again...


But it might still be something bad/strange with the calculator storage memory...

Hmm.. well you never know it still may be related to the clocking code :-P

If you can check Tetris and Tennis that would be nice. Those won't load data from the OS in the middle of the game as often, so it would be good to know if it is related to file reading.

I've just tried Zelda a dozen of times in a row, without transferring anything
(so always the same files, unless they're modifying themselves :P)
.
I did get the beach-freeze on each try
(with the busy indicator appearing at that moment if it wasn't already shown before)
, except on the very last one.

On this very last try, I've let the opening-animation loop 5 times without getting the freeze.

The busy indicator does indicate that it is happening during file reading, as that's the only OS call I ever use while actively playing. Luckily the CG-50 has much more RAM so we may just be able to load the entire game into memory on those calculators, I'm just not sure how to access it yet.
