RevEng Posted December 11, 2022 Share Posted December 11, 2022 It was a treat to drink my morning coffee and watch this! I always find myself wandering a bit, thinking along the lines of "hmmm... I wonder if they did X to achieve that effect, or maybe it was Y." which adds to the fun. Congrats @Eagle and @playsoft!!! A solid showing from both of you on our little but growing platform! 7 2 Quote Link to comment Share on other sites More sharing options...
Trebor Posted December 11, 2022 Share Posted December 11, 2022 It looks and sounds superb overall, but what I am really impressed by is the pace. It would still be impressive at a fraction of the animation speed shown. I'm really blown away by how quickly and well animated it demonstrates in addition to the exquisite sound. An absolutely fantastic job! 7 Quote Link to comment Share on other sites More sharing options...
+Stephen Posted December 11, 2022 Share Posted December 11, 2022 Sorry to be a pest - can I get a timestamp for the particular demo so I don't have to scan through a 7 hour video - the embedded link is not playing, and clicking the link takes me to the beginning of the video on Youtube.

Start at the 5h40m40s mark - it begins a little after that. And this is one impressive demo. Don't think I've ever seen a version of it before that divides the screen into quadrants like that. 2 Quote Link to comment Share on other sites More sharing options...
Eagle Posted December 11, 2022 Author Share Posted December 11, 2022 @Trebor I had to slow down (I even added some NOPs in loop before) so I decided to make full screen and add some sprites IMHO was something wrong with music in BadApple, I checked now on my console and sounds different 🤷♂️ I'm attaching SN Cart Demo but if you want to watch you need make own cart (files attached) Also no NTSC friendly and no signature.

Like in A8 world they using SAP/RMTLZSS. There is also nice player in 6502 using Exomizer https://github.com/simondotm/vgm-player-bbc I am currently porting the driver for cc65 and 7800. I chose the vgc variant with Huffman extra stuffing. For Wizzy I hope to have small, catchy beats that fit into 4096 bytes that I can play from the $d000 bank. Learning to compose on Furnace tracker is going to be a real learning experience for me. But I realized that I do not know where the chips are coded on the SN cart. My guess is: SN76489AN_BASE = $420 COVOX_PORT = $43F Correct? Edit: I have been enjoying your SN-cart ROMs. Pretty cool things you can do with it. My use of the cart will be much more conventional. The bank switching design really opens up a new way to write small graphical adventures on the 7800. Thanks for a great design @Eagle 1 Quote Link to comment Share on other sites More sharing options...

This is compatible with DragonFly (4ch uses $430-$433) SN76489AN_Base = $43F Remember that you may need few Nops because SN need delay 32 cycles after writing data (but if you will use compression should be no problem, delay will be anyway ) Edited January 11, 2023 by Eagle 1 Quote Link to comment Share on other sites More sharing options...
Eagle Posted January 15, 2023 Author Share Posted January 15, 2023 @karri looks like Huffmunch is good for SN I packed bin files with huffmunch and they looks shorter. Also player is short, not in RAM and using only 9 zero page bytes. I made small example - song Collision Chaos from 24508 bytes to 5253 (exo file was 6948) SN cart has 2x16KB ram, so I copied song in higher 16KB and I put 160B Rayman graphics in to lower 16KB ram I'm swapping RAM banks on NMI on the bottom of the screen. Maria is reading lower Ram and SN player is reading higher Ram. This is just proof of concept.

+karri Posted January 16, 2023 Share Posted January 16, 2023 This is really rocket science! I read through this a few times. For wizzy this would solve one of my biggest space problems. In later stages of the game I have a need of letting some graphical effects remain on the screen while other actions continue. Typical actions like casting an ice spell or a fire spell should continue even if wizzy transfoms to some other shape. The dual RAM idea would allow me to keep the music running without taking up space of the special effects. I could keep the last free RAM block for text/special effects. Thanks for sharing these ideas. I would never have discovered this by myself. 1 Quote Link to comment Share on other sites More sharing options...

If you updated DragonFly recently then yo can use this extra 16KB as well. It's is compatible with SN cart Hotspot at $FFFF - bit 0 change between lower and upper 16KB Avoid bit 1 and 2 on SN cart (this is for control A8/A9 line ram) This extra ram in DF was used first time by Paul in 1942 game for extra Pokey music Also remember that banks $Axxx, $Cxxx, $Exxx can use only first 256KB If you want reach above 256KB you can only use $Dxxx bank Quote Link to comment Share on other sites More sharing options...
