Yes, good idea. I'll look into that. Presumably there's an easy way to autodetect PAL/NTSC. [EDIT] Is reading the vertical screen origin (PEEK(36865)) reliable?nbla000 wrote:I suggest you to do just one version for both PAL and NTSC machines with Joy support too.
Interesting, I didn't know that. Thanks for the explanation and the fix. I'll put that in as soon as I can.Assuming that you use a text file and DASM simply change the ORG $1000 with ORG $1001 or ORG 4096 with ORG 4097 and remove the first 0 byte
Thanks!TMR wrote:i've added a news item to Oldschool Gaming
The location #36865/$9001 contain the actual vertical position but the user may change this value before to start the game and you may get a bad info, the best way to check if you are working in a PAL or NTSC machine is to look these locations in rom:Kweepa wrote: Yes, good idea.

PAL:
$EDE4 0C hard H screen position / #60900 = 12
$EDE5 26 hard V screen position / #60901 = 38
NTSC:
$EDE4 05 hard H screen position / #60900 = 05
$EDE5 12 hard V screen position / #60901 = 18
Mega-Cart: the cartridge you plug in once and for all.

This version use video memory too so in real vic you need to start the game typing RUN: [RETURN] not simply RUN [RETURN].
Using video memory is a little bit dangerous because if, for example, the user move up the cursor and type RUN: [RETURN] from the first row, the program crash.
BTW there is an elegant solution to this problem, by using Pucrunch the file will be 3,5K so video memory is not used before the user type RUN.
I need to post the pucrunched version ?
About Mega-Cart addition, may i consider this version the last version ?

First thought is BUGGERY. It shouldn't look like that. Does it always look that way, or is it random?
I just downloaded the D64 and the PRG and played through to that point with each and the room looked fine - the same layout as the first room but with a doorway on the left.
I know it's asking a lot but could you try something for me? Could you redownload the D64, autostart it and then record your progress to that room using VICE's recording history (Snapshot menu)? And upload it somewhere?
That would be great!
And sorry for the problem!
[EDIT]
Actually, if you haven't started yet, could you possibly try it with the latest version (I fixed a bug with some later equipment and pucrunched it).
