Been playing the Re-Console modpack for Minecraft to get that nostalgic feel. Since Iris was installed, I downloaded the “Super Duper Vanilla” shaderpack to see what Minecraft could have been like back in TU1 if the cancelled Super Duper Graphics pack was around then.

You can download the worlds ported to Java, or I’m sure the old MC360Edit would still work, or acquiring a disc and playing it while never connecting to the internet. Discs, while never really changing appearance, were released with varying preloaded Title Updates, so a few are available. It is possible! For me I got the Java ports, I believe from here
