#3937824 Legend of Silverpeak RPG

Agreed!  But, yeah, I suck at music and sound effects.  I'll be adding sound to the game eventually, but I'd definitely need to collaborate with someone to help with music.

I'd be willing to help out on some music. Will you be using POKEY sound, or just TIA ... or POKEY music plus TIA sfx?

As it is character based, it is Antic 2 .

Antic 4/5 with GTIA changes the color mappings. You get 14 of the 16 colors, and all 9 Graphics 10 colors, but some of them change in inverse.

This is partially useful for me when building displays using my ICE graphics modes. I've done experiments using Antic 5 to get about 60 colors onscreen.

What's so special:

On board POKEY and Yamaha sound chips for upgraded sound.
SIO ports for peripherals plus ability to plug in an XEGS Key board and turn it into a computer.

Kind of funny that you are only now able to hear the music you did on the real deal.

It really makes a huge difference!

I will resume working on my project soon.

Thanks to my wife Beverly ... I got an early Christmas present ... we sent off for an adapter for my 7800 ProSystem, and I powered it up for the first time in 30 years tonight:

It all works perfectly! :)  Can't wait to start using it to develop my Sky Scraper game, and also add it to my music studio!  One thing:  You have to keep the console absolutely still, or it will glitch.  May need to be opened up, and the dust of 30 years blown out of the cartridge port. :)

Suggwstion for a future G2F:

Ability to render GTIA mode pictures while in antic 4/5 ... This allows for low - res GTIA pictures and would be very helpful to me.

Awesome work, man. Awesome.  I don't know about your software, but a lot of the Atari 8-bit enthusiasts are going Dual POKEY route. While most of us 7800 fans are lucky enough to get single POKEY action, some add ons like the XBoard supports Dual POKEY in the 7800. You could totally roast the NES versions - and SMS too - by going that route with 8 music channels and still using the TIA for 2-channel audio SFX.
Regardless, wow, I am totally blown away. It's a good time to be a POKEY fan.

Or have 4 16-bit audio channels with perfect note accuracy and extended range, regardless of waveform.

One helpful hint:

If you are doing title screen music, set the POKEY into 16 bit mode where you have one 16 bit channel and two 8 bit ones, and use one of the TIA channels for percussion. This reproduces NES music with greater accuracy.

#3897471 My 8-bit Games Porting to 7800 in the works

I found a way to record videos with the ProSystem emulator. I have to use a program like OBS Studio to make a recording.
This is an early Work-in-Progress. I am trying to see how many animated objects I can have onscreen at once. They will be moving around once I figure out more stuff.

One helpful hint: MARIA DMA goes by zones. So the fewer objects you have in a horizontal zone, the better. This means you can also split things vertically and not use up a lot of DMA.

No I got those issues sorted. Currently working on bank switching at the moment.

#3883620 Altirra 2.90 released

Posted by Synthpopalooza on Sat Nov 4, 2017 2:18 PM

I would like to see an emulation of Sophia ... I.e. independently programmable text color in Antic 2, 16 lumas in non GTIA mode, and no Graphics 10 shift.

#3875871 Looking for 7800 programmer to assist porting a game

Posted by Synthpopalooza on Tue Oct 24, 2017 11:27 PM

Well Venture is now one of the listed Atari 7800 games to be ported over. I can make the sprites multi-colored and sprites not be limited to the player/missile sizes. I made up a small image of what the sprites may look like on the 7800. I can make it more arcade like.
We will be producing these games for the stock 7800 and will not be taking advantage of any special upgrades or modules, like that XM module.

You could do this game in 320 mode. 320B for your player and 320A (mono colored sprites) for the enemies and the character map. I think it would look great.

#3875790 5-color mode with almost no restrictions

Posted by Synthpopalooza on Tue Oct 24, 2017 8:39 PM

The first thing that comes to my mind is this from NYD 2010. Mode F & 4.

That is actually ANTIC 4 with the GTIA alternating with mode 11 and some HSCROL trickery to reduce the area needed for PF2/PF3 conflicts, if I remember rightly.

I think Rybags also used the PMGs here as he described above ... This basically gets 96 colors (roughly 14 chroma x about 6 lumas though they aren't all freely usable)
