I think Covox is using IRQ, so you may need set IRQ in header.

And it's running SN cart demo. Testing and adding all new features will take some time but will be lot of fun sn2.mp4

It’s alive 😂

We can mix 160 and 320 modes 🥳

Transparency "fix" is base on how Maria is writing to LineRAM (we doubled LineRAM) You are asking for changing reading. In 320B mode you already have 2 bits per pixel in gfx data, just Maria can't write this to LineRam. 320C is different and possible for MariaECi but only because Maria it's done from scratch in FPGA and have no limitations like normal Maria. MariaECI can read up to 500 bytes per line (normal Maria about 130 max) For 320C fix you will have to double amount of data. With transparency "fix" you can put 2 sprites 320C on top of each other. ps. Just came to me that with doubled LineRAM we probably could try mix 160 and 320 modes 🤔 🤯 In 5 bytes header we could use one spare bit to change CTRL read mode on the fly I need ask smarter people than me if this is possible edit: hmmm we could use bit 0 for mix mode but also use bit 1 for 320px sprite movement

Bit 4 in DLL entry will enable Extended Hires mode for MariaECI, also DLL entry will take 7 bytes give some extra features like for example 32 bit address for Maria gfx bank SN² cart will not support this but 7800GD could easily and it's up to @SainT. When we finish testing SN² cart and MariaECI I will share all details. Yes. Me too. But this is for YM2612. For example we have YM2151 for few years for now and no one is using. I did few demos, Paul and Mike did some players but Midi style. Playing YM2151 vgm it can take up to 500 bytes per frame with 32 cycles delay between writes. No chance to get very good music in game. All arcades and other machines with YM2151 have extra CPU Z80 for just playing the music! I don't want Z80 so we will use FPGA to play VGM but you don't have to use it. Instead of YM2151 we should use YM2413, but someone decide long time ago to put YM2151 in XM module 🤷‍♂️ I was planning to put YM2413 on SN cart and even I sent few chips to Rafal (BTW TailChao was planning use YM2413 for Rikki but he was afraid of fake chips) But we have now SN² cart

It's support only mapper. Rikki&Vikki music 500KB 7800GD music 90MB

SN cart "only" use banking for $Axxx, $Cxxx,$Dxxx and $Exxx, new cart will do $8xxx,$9xxx,$Bxxx as well 8KB banking for RAM FPGA player for VGM (just give him address in rom and will play) Pointers - you can read any byte in rom without changing banks Covox DMA SN76489 stereo, Pokey, YM2612 and more It's compatible with SN cart and you can send rom just using USB-UART cable Also documentation will be publish so any one can make own cart. I'm not gonna lie this is very demoscene oriented cart but in good hand will help make amazing games.

SN² cart is on his way, but MiSTer core for old SN cart is almost ready (base on @Kitrinx core but our version will be only for devs so far) New SN cart for 7800 will support features from MariaECI and help develop on both platforms. ps. sorry, no sound because my video grabber for some reason stopped recording audio 🤷‍♂️ 2023-08-10 18-02-08.mp4

Ok. I will try to use $480 Thanks.

I need 6 bytes for each pointer, MariaEci use 4 pointers but I'm thinking to use only 2 for 7800 $47x it's for XM module (I think only emulators are using) $46x for YM family $43x it's for Covox but also for 2 SN chips and Covox DMA (we had to change MiSTer code because covox is repeated up to $43F) I can try use $480 but imho it's better to utilize existing space.

Thanks, I just need space for pointers in my new cart. If you don't mind I will use addresses from $421, unless you are planning to use them in the future?

Are you using only $420 or address is repeated up to $42F

Nice to see another game using YM2151.

For those who do not have the game Rikki&Vikki I attach ADPCM tester. You can check if there are any volume problems. ADPCMtest.zip

I'm working on this to make pixel art people life easier. Also in MariaECI we are fixing 320 modes, maybe 7800GD will do this same.

Yes. I was confused and had to check my code Line 69, 126 need correction.

Hmm 🤔

"Fixed" transparency for hires modes in MariaECI for Atari XL/XE When bit 4 in DLL entry is ON then extended LineRam is used (two 160x5 bit - 1600 bits) @SainT any chance to do similar "fix" for Maria in GD7800 in the future? NewLineRAM.mp4

Looks like @emkay has been banned on AAge, but you can try reach him on AOL https://atarionline.pl/forum/comments.php?DiscussionID=6972&page=3#Item_8

Yep. My dog looks too sober 😂

Nice. Few months ago I tried conversion from nes to 320C mode Should look better if you will draw from the scratch

You can get Rikki from here https://store.steampowered.com/app/893690/Rikki__Vikki/ then you need to convert with SainT tools
