Of course, but maybe one of them would be enough.

Edit: Veronica is ready to buy.

I have made post on AtariAge too...

I know there is Veronica. It is beautiful but price of 65816 is higher than STM32 (10 Euro).
I know there is very nice Tomek8 but as I wrote PIC is not so powerful as same priced STM32...
But you can get STM32 in huge quantities...
I somewhere read something exactly same exists for ColecoVision or 2600...

For example 6502 emulator on STM32:
GITHUB
https://github.com/BigEd/a6502

"On that dev board, the CPU runs at 168MHz and the emulated speed of the 6502 is 18MHz."

Thats almost 10x+ faster as original Atari.

And there is also 180MHz model STM32...

Price is 10Euro... for  STM32F407VGT6:
32 Bit Microcontroller, Ethernet MAC, Camera Interface, ARM Cortex-M4, 168 MHz, 1 MB, 196 KB, 100

Maybe we can have Ethernet too on that cartridge for multiplayer games.
I can imagine NUMEN engine shooter and LANPARTY! like QUAKE!
Or DUNE2 / Settlers 2 game !!! Multiplayer / online...
This will adds new dimension to our ATARIs... Playing games together. New speed for CPU.
Lot of sprites, pokey sample playback etc etc... So it will be turbocard but also will accelerate graphics and sound.
Plus online multiplayer gaming or local LAN party as bonus.

Lets brainstorm this.

I can imagine games in hires with huge sprites. Or 160x200 games with ultra fast scrolling (space shooter) for example.
Or vector game with samples. Or 3D demo looking almost like from Amiga 500...
When price of cartridge will be 20-30Euro. Everyone will be able to buy it.
