[gambler172]

Hi Franko

checked your latest version.Unfortunately touching the bed,raises my score and not my hitpoints

And the titlescreen is not shown correctly.Draker is completely missing.And QUEST is shown only at half.

Try this. The PAL version of Draker Quest:

test_beta2_pal.bas.bin

test_beta2_pal.bas.a78

Hi Franko

NTSC is no problem,cause i have also NTSC

systems.I tried the PAL version on one of my PAL

systems,but the titlescreen problem and the hitpoints problem are the same

I'm using MESS and I have no cuttle cart 2 to test but this is what I get for the title screen in NTSC:

 

 

I don't know if I mentioned this or not but the HP counter only goes up to 100.

Has anyone else with a Cuttle Cart 2 experienced what Walter has mentioned?

Hi Franko

what Mess version do you use?

I used Mess 1.53 on my laptop.The titlescreen is correct here,but there are many bugs.Try to play it on Mess,until you get the first key....

But raising hitpoints in the bed,works here

If you send me your Email,i could send you some pics,i made with my ipod.

Btw....keep up you great work

I'm not sure but it could be version 0.155. There's a tutorial and how to install it with XM support here

[gambler172]

Hi Franko

i used Mess 1.55 and your game works great.

However on my CC2,it has the bugs,i told you about.

But i also asked CPUWIZ to burn it on a board and check it about the bugs,i had.

The title screen is totally messed up on real hardware, using my Megacart board.

Hi Franko,

 

It looks like the problem is you're dim'ing memory locations that aren't actually RAM locations in the 7800.

 

         dim title_parta_x=$3006
         dim title_parta_y=$3007
[...]

The "extra" user RAM not used by 7800basic runs from $2200 to $27FF, so your dims have to stay in this range of addresses.

 

A couple points to help you trim the usage back...

• You use these to values for coordinates to "plotsprite" the title graphics, but you can just use constants directly in the plotsprite command. No need to define variables if the sprite doesn't move.
• You're not counting up the memory locations in hex. The next memory location after $2209, for example, would be $220A.

Cheers!

It needs to be determined, why it does work in MESS.

He's mentioning something about enabling XM support in MESS... maybe that's the key issue?

[+RevEng]

It needs to be determined, why it does work in MESS.

Totally agreed. I threw it on my mental TODO pile yesterday, and took a quick look at it this morning.

 

It seems like the a7800 MESS driver sets up $3000 as part of a RAM mirror. Looking appendix 1 of the 7800 Software Guide, it seems to support that idea...

...it seems the docs (and MESS) need updating, but when I have the time I'll first need to go in and verify all of the mirrors.

 

Does the title screen glitching dynamically move, like it was reading values from a floating bus?

 

 

@Mord: Good guess, though it seems to happen even without XM enabled.

[+frankodragon]

Try the latest build:

test_beta2.bas.bin

test_beta2.bas.a78

I'll try the new ROM tonight.

 

No flicker, just this (looks like all sprites are stacked on top of each other)...

[+RevEng]

Cool. If I remove the higher mirror addresses from MESS, this is what I get...

 

 

I still need to do testing to see what sort of values I get back from a real 7800 for this address space, but it looks to be on the right track.

[CPUWIZ]

I have been able to map a real RAM chip into $3000-$3FFF, for what it is worth.

[CPUWIZ]

Come to think of it, it is impossible for it to be a RAM mirror, my MCP cart uses $3000 as the hotspot to write to. That would blow up the mirror location and it doesn't.

[+RevEng]

Yeah, there's the HSC too. It looks like Eckhard checked this out a while back too.

[CPUWIZ]

Yeah, I just remembered that I touched on this subject last year.

Yeah, your new a78 looks like that now, even in my fixed MESS. I was showing WIZ how your previous version looked.

I had to change some dim values like RevEng said as some had non-existent values. Other values had to be changed as I got some weird flickering results with MESS but let me know if there is weirdness on actual hardware.
