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

greetings Walter

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.

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

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.

greetings Walter

 

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.

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.

I'll try the new ROM tonight.

 

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

Hi Guys

do not forget to play the game.....while the game in Mess works very well,there are some bugs,i reported.

greetings Walter

Try the latest file http://atariage.com/forums/topic/229946-working-title-draker-quest/?p=3199436

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.
