A very challenging game! Love the cute penguin and the tunes. Congratulations to Buresto Faiya for its first game: a very original puzzle game -I would say mind bending- with an excellent execution. Any clues about how to find the PONG game included within? Love Easter Eggs!

Once again, congratulations to SapphiRe and KNM. Hope to hear from you soon!

Thanks a lot pitpan!

And no... there are no clues! You need to play and find the secret passwords to unlock the secrets and surprises of the game

We want more details about your future projects!

Anyway, it'll take me some time to finish NAMAKE'S... I'm feeling a bit clumsy when it comes to smart penguins!

Hmm, the game resets on a 8250, right after the first step of the instructions...

Hmm, it doesn't work on a 8245 (at least not the one in openMSX)... Nor a 8220, VG 8230 or VG 8235.

It also doesn't work on a VG 8020/20, but it does work on a VG 8020/00. RAM/slot problem?

Hey pitpan!!Check your mail right now!SapphiRe has sent to you the official flyer of the game ( I´ve finished 10 minutes ago!)

RAM/Slot problems... I guess it's impossible, the game doesn't play with slots...

PitPan, the MSX2 where ee tested Namake's at Barcelona's RU was a 8245, wasn't it?

The flyer is already on-line. I like it very much, KNM!

About the reboot problem, it think that it might be a stack overflow problem. Does the game setup its own SP value or asumes the current one as ok? Perhaps it is related with the way Manuel has loaded it. More details, please!

At Barcelona's RU we tested it on a Philips VG-8235 MSX2. No problems at all.

By SapphiRe

Master (253)

21-12-2005, 20:56

The game doesn't touch SP value, and I've checked that stack doesn't overflow...

It's weird...

By pitpan

Prophet (2559)

21-12-2005, 21:00

No, I was suggesting that the problem was related to the ROM loader used by Manuel. If you assume that the stack is setup correctly and do not touch it, but the ROM loader moves it, there might be some problems.

By Manuel

Enlighted (7234)

21-12-2005, 21:03

I didn't use a ROM loader, I just used openMSX.

If this is the problem it's easy to fix, just adding a ld SP,xxxx

Hmm, it also crashes on a National FS-4000.
I have to find what these machines have in common!

On a Sony HB-F500P it just hangs with a black screen at that point. Could it be the sound routine? (Hm, but it does work outside of the demo.) Also resets on an F700D.

It does runon Panasonic FS-A1.

Always crashes in the demo? It uses no special routines...

Sony HB75 : Works fine, both intro & game
Philips NMS8245 : Idem
Panasonic FS-A1FX : Idem
Panasonic FS-A1ST : Idem

Seems to work fine in all machines...

How exactly did you test it? With ExecROM?

By jltursan

Paragon (1340)

21-12-2005, 23:10

Yes, only EXECROM 1.2c. Without optional parameters...

OK thanks. It seems we found a bug in openMSX.

By SapphiRe

Master (253)

NOP! BUG WAS IN THE GAME!

The problem was really weird, I will try to explain it:

In the game there is a routine which redraws the board and the stage. This routine has two entry points. If you enter using the first one, a pointer is initialized properly, but it's not initialized when using the second entry point... used only in the demo.

What's wrong? Well, if not initialized, the pointer value was $FFFF (subslot register) and I use this pointer to save the moves for undo feature. When a move's saved the value of bits 6 and 7 is always 0, so: if a computer has the ram in a expanded slot and not in subslot 0, the game will crash if you want to see the demo before playing. Not in other case (unless you see the demo more than 90 times).

Now I've corrected this weird bug and I've sent a fixed ROM to Robsy. I hope he'll publish it as soon as possible.

Thanks a lot Manuel to help me find this bug, I hope you enjoy the game

Yep, I love the game!

And thanks for finding this out. However, how come it did work on your real 8245??

By Manuel

Enlighted (7234)

22-12-2005, 22:34

Hm, it might be the fact that in openMSX all RAM is initialized with 0xFF, while on real MSX this may be different, depending on the RAM chips used...

There seems to be another bug in the game:

Ok. I'll patch the PT3 player routine to mask the PSG reg#7 value. The patch seems to be like:

AND 63
OR 128

to the value of 7th PSG register, isn't it?

I hope a new fixed version will be available this weekend... These days I have no much time, I'm taking care of my parents, sorry.

Can someone please send me the old version with that bug in the demo? I'd like to test a new openMSX feature that can detect reads from uninitialized memory....

Thanks in advance!

Cool!. Seems that "Kungfu packing crate maze" is one of the most popular games from James Stephens!
