42bs Posted May 15, 2020 Share Posted May 15, 2020 Just want to spread the news: http://outlinedemoparty.nl/#compos I entered a 128b intro. So, let's go Lynxers, show which platform really rulez! 3 Quote Link to comment Share on other sites More sharing options...
LordKraken Posted May 15, 2020 Share Posted May 15, 2020 (edited) Did you read the footnotes? (*) 128b intro - ASM gods only. I'm definitely out ... but I will cheer for you and the lynx Edited May 15, 2020 by LordKraken 1 Quote Link to comment Share on other sites More sharing options...
Songbird Posted May 16, 2020 Share Posted May 16, 2020 I'm confused... on the first page it says 128 bytes, then on the next page it says "no file size limit." Quote Link to comment Share on other sites More sharing options...

+karri Posted May 16, 2020 Share Posted May 16, 2020 This 128 bytes is insane! @sage and I thought we were hard-core developers when we wrote games for a 1024 byte competition. Available on Lynx Reloaded. My Ottelo entry even had AI built in. So I bet it was able to beat any average Othello player. In a way I would like to participate in this 128 byte competition too. The only problem is that the encrypter creates multiples of 52 bytes. Not good. The only solution is to have a single block bootblock followed by 128-52-1 bytes. Fortunately there is plenty of time as the deadline is on Thursday. Now I just need to figure out a game that can be coded in no space at all...

And spent 95 bytes for nothing. The palette is still random. And I have just 33 bytes left. If I set up the palette it leaves me 1 byte for the game. Have I misunderstood the rules? Or should I expect that the ROM has already intialized the chips to a decent state? Quote Link to comment Share on other sites More sharing options...
LordKraken Posted May 16, 2020 Share Posted May 16, 2020 Maybe use the plasma demo as a start? https://github.com/42Bastian/lynx_hacking/blob/90284aec1b96a2312acbb1045d557ecfd398d8b0/248b/plasma2/plasma.asm Quote Link to comment Share on other sites More sharing options...
Fadest Posted May 16, 2020 Share Posted May 16, 2020 (edited) From the rules of 128b intro : Quote Maximum file size is 128 bytes for DOS and other platforms/formats which do not require an executable header. For other platforms, standard header size does not count towards the 128 byte limit. However, using the header to store custom code/data is not allowed.

I submitted the pure binary w/o BLL header of 128 bytes and one w/ for handy as well as a one lnx. BTW they have also a 256 bytes compo Edited May 16, 2020 by 42bs Quote Link to comment Share on other sites More sharing options...
42bs Posted May 16, 2020 Author Share Posted May 16, 2020 (edited) My understanding (and challenge) is that we can assume the state of the Lynx after the ROM did load the bootsector. Sure, this is unfair compared to an Atari ST, where the palette is set. But that is the challenge ? Edited May 16, 2020 by 42bs Quote Link to comment Share on other sites More sharing options...

Packing does not do any good, no redundance. Quote Link to comment Share on other sites More sharing options...
42bs Posted May 16, 2020 Author Share Posted May 16, 2020 Karri, yes, Mikey and Suzy init hurts. But, check out the ROM, at least Mikey has a minimal setup! And, you might want avoid interrupts. Quote Link to comment Share on other sites More sharing options...
42bs Posted May 17, 2020 Author Share Posted May 17, 2020 _But_ beware: Testing on Lynx is mandatory. Just extended Plasma3 and tested it an hour long on Handy just to discover: It does not work on the real thing: FD94/FD95 is write only but on real hardware.

42bs Posted May 18, 2020 Author Share Posted May 18, 2020 Arg, need to squeeze 10 bytes out of my 256b entry (well, 249 as it is Lynx) to get nice colors Though, green is also a nice color ? Quote Link to comment Share on other sites More sharing options...
42bs Posted May 19, 2020 Author Share Posted May 19, 2020 256b entry submitted, time to relax and flush my brain from thinking about how to get an extra free byte here or there ? 1 Quote Link to comment Share on other sites More sharing options...
+karri Posted May 19, 2020 Share Posted May 19, 2020 Great! I decided to skip the competition. Instead I modded a 2.8" display with shattered glass, an old 1st generation PiZero with broken SD card socket + a DIY cardboard Bluetooth speaker with a broken Bluetooth. The result was a stylish MP3 player. 1 1 Quote Link to comment Share on other sites More sharing options...

Acutally, size limited programming has the advantage that I do not have to think about a lot of GFX and most importantly music. Quote Link to comment Share on other sites More sharing options...

Igor Posted June 19, 2020 Share Posted June 19, 2020 Finally was able to add these to the game database. Wanted to hold off until I had the events feature working - https://atarigamer.com/lynx/event/OutlineOnline/5662335972671488 1 Quote Link to comment Share on other sites More sharing options...
