MariaEci - FPGA VGM player Yamaha 2612 + SN76489 We should have this in SN2 cart and MiSTer very soon. So now we can have vgm in game music from Yamaha 2151 or 2612 Btw SN2 cart for devs will have SD card IMG_2871.MOV

IMHO something is not right. If I remember correctly Portal is using second Pokey for music. Before update 7800GD has missing second pokey but it was playing music (?) Update fix problem with IRQ on another Pokey (1?) Sorry I don’t have 7800GD so I can’t check. We may need @playsoft for some more info.

Covox was played on IRQ, so if Pokey was missing then Covox couldn't be played.

Yes https://github.com/Kitrinx/Atari7800_MiSTer Working ok. Yamaha is playing. Are you sure you'r using IRQ for detecting YM? Because is playing on JS7800 and I don't think that JS7800 have IRQ for YM. No, JS7800 is not detecting. Looks like it's working ok on MiSTer, but Shinobi is not. edit: BTW you haven't set Yamaha IRQ bit in your header So I'm even more confused edit2: Are you using bit Ready to detect YM? 🤓

I've checked Portal on Mister and Covox is working when I switch on IRQ in the menu. So file is ok, but header should turn on IRQ anyway, but dosen't. I don't know how old MiSTer core is, meybe is not update to new v4 header. Shinobi is failing in MiSTer as expected, because:

@Trebor I don’t think that A7800 emulator supports Pokey or Yamaha IRQ But I’m not sure.

Nope

and YM2151 20230814_222424.mp4

Today we have Yamaha 2612 from Sega Megadrive on Atari 7800 SN² Cart 20230814_201503.mp4

Just out of curiosity, could someone check out a Shinobi demo that uses the YM2151 IRQ interrupt? I hope I set all the bits correctly shinobi.a78

It’s like 7800GD but for AtariXL/XE SN2 cart playing in Dual Pokey 🥳 20230814_033306.mp4

Mat is trying to put SD card and HDMI on SN2 cart but I don’t want it. Next step for SN2 cart is using FPGA for building Display List. So you don’t need worry about scrolling screen horizontal or vertical.

Yes. We will try to have 6 pallets x4 colours for 320C in Hires extended mode. But no idea what to do with 320D

I have no idea. Will work on MariaECI for AtariXL/XE and probably on MiSTer for 7800 I'm not planning put Maria on SN² cart, but maybe on day I will make SN³ cart

Yes

Only @SainT can investigate. Looks like IRQ not working? I can try to write some test tomorrow.

Do you have the latest firmware update? There was problem witch covox at the beginning. Anything else what I can think of that IRQ are other way around in 7800GD In header spec bit 0 is for pokey $450 (I would expect keep in order and have $440) Try this version. I have set IRQ bit for Pokey 2 (but Covox is playing on Pokey1 IRQ) Portal (PAL) (20210331).a78

@Defender_2600 quick test on my old tester for 320A Bellow 8 sprites in 320B, each has own 3 colour pallet!!! 😍

Sorry, I didn't notice that Covox bit is missing as well. Try this version. Portal (PAL) (20210331).a78

@-^CrossBow^- try this version (sorry I can't check because I have no 7800GD) Portal (PAL) (20210331).a78

7800 MiSTer core for SN cart (4KB banking, sound chip SN76489, ram A8/A9, etc.) is finished. It's unofficial version only for devs. Anyone interested please PM me. 2023-08-13_15-14-48.mp4

No. Just 32MB ram. But in special mode (bit4 DL) we use 32bit for address ram for Maria.

Hi @Defender_2600 I just spoke with Mat and he will increase LineRam so we can have 8 pallet in 320 modes. For 320C I would like to have P0C1 P1C1 P2C1 P2C1 and P0C3 P1C3 P2C3 P3C3 and.... I'm thinking about 320D but nothing coming to mind. I hope you will like it MariaEci FPGA has 25K LUT's and Maria core was written from scratch and it's taking about 30% MiSTer Maria LUT's. I hope that will be possible to increase 7800GD LineRAM and fit in FPGA Would be nice to have new modes not only for MariaECi and MiSTer but also for 7800GD
