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!
By KNM on December 21 2005, 18:45
snif,snif - i´ve got no words -

Thanks a lot,pitpan!
By SapphiRe on December 21 2005, 18:48
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

By pitpan on December 21 2005, 18:59
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!
By jltursan on December 21 2005, 19:10
Hey!, congratulations for bring us such a good game and for keep us sticked to the forum till the end, what a day! uh, Sapphire?
Really well done, I really like the animated instructions, it's a very professional touch!. Btw, good work with the music too KNM, very catchy!
By viejo_archivero on December 21 2005, 19:56
A very good one, guys!. Keep them comin'!
By manuel on December 21 2005, 20:06
Hmm, the game resets on a 8250, right after the first step of the instructions...
By manuel on December 21 2005, 20:20
(Does work on an MSX1 and a turboR, though... weird!)
By SapphiRe on December 21 2005, 20:22
it works on a 8245 too... weird, weird...
By manuel on December 21 2005, 20:28
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?
By KNM on December 21 2005, 20:34
Hey pitpan!!Check your mail right now!SapphiRe has sent to you the official flyer of the game ( I´ve finished 10 minutes ago!)

By SapphiRe on December 21 2005, 20:36
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?

By pitpan on December 21 2005, 20:46
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!
By pitpan on December 21 2005, 20:47
At Barcelona's RU we tested it on a Philips VG-8235 MSX2. No problems at all.
By SapphiRe on December 21 2005, 20:56
The game doesn't touch SP value, and I've checked that stack doesn't overflow...

It's weird...
By pitpan on December 21 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 on December 21 2005, 21:03
I didn't use a ROM loader, I just used openMSX.
By SapphiRe on December 21 2005, 21:04
If this is the problem it's easy to fix, just adding a ld SP,xxxx

By manuel on December 21 2005, 21:07
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.
By SapphiRe on December 21 2005, 21:13
Always crashes in the demo? It uses no special routines...
By jltursan on December 21 2005, 21:14
I'm going to test it right now on my machines...keep tuned...
By jltursan on December 21 2005, 21:27
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...
By manuel on December 21 2005, 21:41
How exactly did you test it? With ExecROM?
By jltursan on December 21 2005, 23:10
Yes, only EXECROM 1.2c. Without optional parameters...
By manuel on December 21 2005, 23:38
OK thanks. It seems we found a bug in openMSX.
By SapphiRe on December 22 2005, 12:16
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
By pitpan on December 22 2005, 12:41
Fixed!
By manuel on December 22 2005, 22:12
Yep, I love the game!

And thanks for finding this out. However, how come it did work on your real 8245??
By manuel on December 22 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...
By manuel on December 27 2005, 14:39
There seems to be another bug in the game:

http://sourceforge.net/tracker/?func=detail&atid=421861&aid=1390211&group_id=38274
By SapphiRe on December 29 2005, 12:00
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.

By manuel on February 11 2006, 22:18
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!
By manuel on July 01 2006, 20:28
Heh, check this out: http://www.thinkfun.com/tipover/index.htm

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