Yeah, I have no idea how rugby's scoring system works let alone how to actually play without getting kicked out.

It looks like a really cool Sonic remake. Anyone up for a calc version?

Well, remember Jump, that one demo released for the axe contest? that seems like it would have similar physics, at least. I would hate to play sonic that slow though it's made to be fast paced.

I think it was for side scrollers. I don't know what collision detection was implemented, though. Also it had some bugs, if I remember.

yeah it was just a fun concept, although making a fully fledged engine with a tilemapper would be quite an undertaking Especially with slopes and loops and stuff.  I think is no wonder that Sonic really never got off the ground

Sonic actually got pretty far...I know because I worked on it. Me and digi have been busy with other stuff. I know I just dont have the time and he must be about the same because I havent seen a RW update in a while.

Sonic is clearly possible on the TI-83+SE, because the Game Gear/Master System used a Z80 at only 3.5 MHz. The weak point here is the graphics. I can't say if TI-83+ would be able to handle both the physics and graphics at the same time, but the extra processing power provided by the SE/84+ models could surely make up for the terrible display interface. Somebody from Sonic Retro actually suggested using a disassembly of Sonic for the Game Gear/Master System and port it to the calculator. The graphics would need to be completely rewritten, but the main game engine might work without too much modification.

Was there ever a demo released for it? I was looking over the "Progress..." thread over at UTI, skimmed would be more accurate, but couldn't find one (nor many pictures of the game or the game in action). Just a little curious because I remember seeing that when I first signed up there but didn't have the time to look over everything.

The difference between our version and theirs, was by far better graphics and we actually had a physics engine. We could release our physics engine I guess if you wanted to roll around some ramps and stuff. But really it was just us getting the engine done. I don't want to make it sound like this is ours and nobody should help because that isnt the case. It's just when you spend a lot of time on something you hate to just give it up to someone else.

The plan was to incorporate jim's tilemapper so really we are pretty close. You'll see an update when Digi is done with RW I'm sure. It kinda sucked that the sonic.unitedti.org site was not put back up, because it made it easier to see some of the progress and mockups we had made instead of searching through a large thread.
