Eurochip + Origachip 1.1

[drussi]

Hello there

Can you help me out with something?

NR 1 I have PS2 PAL 30004R How do I know what motherboard is in it.

NR 2 Will EUROCHIP + ORIGACHIP 1.1 work with my ps2 & can it play backup ps1 & ps2 games without swap.

I am a little lost there If I am right we are talking about two different modchips EUROCHIP and ORIGACHIP 1.1 but ORIGACHIP 1.12 is another type of a mod chip.
What should I buy for my ps2?

Please comment on this Thank you Drussi
