Is it possible to run a Photoshop cs6 with rosetta 2 on a m1 mac ?

The Java 6 that CS6 requires and parts of CS6 itself are 32-bit and Catalina/Big Sur require pure 64-bit applications. Its either Adobe subscription-ware that is compatible with Big Sur, or determining if the Apple Silicon native, non-subscription, Affinity Design and Photo can replace your CS6 dependencies.

Rosetta2 still expects a pure 64-bit Intel binary.

Why not ?

Photoshop, Apple Silicon, and Big Sur | macOS 11 - Adobe ...

Rosetta 2 an emulator built into macOS Big Sur that will enable ARM Macs to run old Intel apps. Rosetta 2 essentially “translates” instructions that were written for Intel processors into commands that Apple’s chips can understand. Developers won’t need to make any changes to their old apps; they’ll just work.

CS6 has issues running on Catalina and Big Sur on Intel Macs

let alone M1 Macs.

I would say at this point you have got more then your money's

worth and is time to move on. Either move to Adobe Cash Cow (CC)

or alternative app.

I’m running Catalina (I upgraded from Mojave) and still need to use Photoshop and Dreamweaver CS6. What I did was make a new partition and installed Mojave on it then installed CS6. Just use Option key at startup to use whichever OS for your needs, Catalina for latest versions of WOW, Numbers, Pages etc and switch to Mojave when I need to edit photos or work on my website. Hope this helps.

I'm running Catalina but created a partition and installed Mojave. Then installed Photoshop and Dreamweaver on the Mojave partition. Just hold Option key at boot up to change between OS.

FWIW, no M1 Mac will run Mojave or Catalina.
