I found out how I could code on the screen without crashing.
Now the setting of HR-routine is done on screen and I have 156 bytes left.

Restart setting of initial values in just a few bytes.
149 bytes remaining....
(saved a byte in another routine)

Re: 1k hires idea, adaptation of Grandpr1x
Done some preparation for bonustime when finishing a round in time.
With the preparation I was able to free a lot of bytes.
Available space now 176 bytes.
The display was too large. The edges of the screen could not be reached.
So I altered the size in width and was able to delete bytes in the displayroutine.
In the DRAW-routine I also noticed an adjustment that would save almost 10 bytes.
Getting confidence to fit the game in 1K.

Re: 1k hires idea, adaptation of Grandpr1x
Due to the shortening of the display the first 30 bytes (#4000-401D) only need 16 for the display.
In the remaining 13 (1 byte is overwritten by plot) I can store the compressed track.
To do this I can store the compressed track in the hires linebuffer, after loading use the screen for the copy from
linebuffer to #4011 and then start the program. The next thing is the reuse of the linebuffer for the visbible track,
combined with the normal function of displaying a line in hires.
This saves another 12 bytes.
188 bytes free for coding.
The gameplay will become a bit different from Grandpr1x.
Grandpr1x keeps you playing when you finish a round in time with extra time.
Roadracer willbe like MarbleRacer.
Drive 5 rounds as fast as possible. time is meassured.
If you want to play the Grandpr1x-variant, upload a Spectrum emulator and play Grandpr1x.

Reset laps and time, restart game added.
Preparation for highscore (might fell off again).
To do
Controls and timing.
Bytes left 138

Re: 1k hires idea, adaptation of Grandpr1x
Drifting in the turns and steering now added.
Since the track is rather small I will not add the breakoutfunction when the turn is too large.
When you hit the sidetracks your speed drops to really slow and you need to built up speed again.
So best races are the ones with as less sidecollission as possible.
Only thing to do is timing and hiscore and perhaps speeddisplay.
Still 69 bytes left.

Re: 1k hires idea, adaptation of Grandpr1x
Game is ready!
The gameplay will be racing 2 rounds in the fastest time.
Your fastest time is saved as hiscore.
The screen has 49 lines of 16 bytes and 2 lowres lines.
As usual I will make a PDF with the source and the P-file will be set in the new games section.

Re: 1k hires idea, adaptation of Grandpr1x
Were there any bytes left?? 
Amazing work as always Dr. Beep!

It seemed that some bytes were needed to prevent overwriting the code.sirmorris wrote:Were there any bytes left??
I left 12 bytes unused for this goal.
Thanks, this was a tough one.Amazing work as always Dr. Beep!
I like the idea that the hires linebuffer is used 3 times.
1) datastorage of compressed track
2) after copying building the visible track in the linebuffer
3) the linebuffer, the display of the hiresdata in highmemory
It is possible to make versions with other tracks.
A corner is 1/8 of a circle. Full track may have 48 parts.
Start/finish must be set between straight tracks.
