Hang On proof of concept

[skyzoo73]

Fantastic Tech Demo of HANG ON for Amiga 500,
which shows how a conversion is made by making good use of the Amiga.

Requires 1 mega of chipram.

This looks great. I didn't mind the Amiga port - many hours of fun!

I think this port is good but as is it looping? I'm not sure how changing sprites may affect it? Just replace the bike with Ferrari and you have Outrun lol.

Looks pretty good but is missing hills. If it can also do hills at this framerate then you have a winner.

A good effort this. I would like to see someone tackle Chase HQ though.

Great work & music !!!

I thought the same while watching the video. Anyway, nice proof of concept.
Cherry on the cake : would love to see the full game like this

[Marchie]

Super smooth, really nice!

[Hewitson]

Pretty impressive, but there's a big difference between a tech demo and a proper game. Once the game was fully implemented I very much doubt that 50fps would still be possible.

The first Hang On did not have hills

[saimon69]

However, it seems the first hang on could be made very close to arcade, i would make a 50FPS with object upgraded at 25 just to have it if i had the skills; might have an outdated gameplay compared to Super Hang On and latter incarnations but is still enjoyable;

And, strangely, another one that could come out very good is TX-1 (if we forget the three screens extravaganza): the game has max 16 colors in screen and fake(!) uphill/downhill

Using Dual Playfield mode for one Copper controlled road layer and one graphics layer is a very smart move. Done well, that makes drawing the road pretty much "free". The cost is obviously a low number of colours per scanline, which is probably why it's not normally seen.

I wonder how much raster time is left...

Impressive stuff for sure, though. Thanks for sharing

[DamienD]

To me, I'm perfectly happy with the version of Super Hang-On that we got on the Amiga

[Bren McGuire]

This is smooth but way too slow. It wouldn't make the cut into a real game.
Look at the original:

Far from " arcade perfectness" as the scroller says.

That's Super Hang On, not Hang On, though.

Provided the frame rate's high enough, "faster" just means moving further each frame, so shouldn't be beyond reach.

[saimon69]

Yup, this is the Hang on we are talking to...

I did pour a lot of coins in this machine, and tried to code my own clone on the ZX spectrum (called Easy Biker), was done - i admit - poorly: using BASIC and draw routines to move horizon lines left and right plus a perceived sense of centrifugal force, occasional side obbjects and some bike - also a rendition of the music (a bit poor too) using the stolen two channel routine from Zombie Zombie (provided by an italian cassette magazine) - sadly might have been lost due to bitrot of the tapes

I think Vroom could be also "proof of concept" for this, and is completed game.

Amazing effort... !

Oops, I stand corrected. All my memories are of Super Hang On I guess. xD

[Adrian Browne]

Super hang on was a favourite of mine back in the day on the a500.

Writing that copperlist competes for bus access though and takes time, especially when all 6 bitplanes are enabled.

Close to none. Using the visual DMA debugger in UAE (v-4 command) when running using an A500/1Mb chip configuration will give you an idea. There are some things that could be improved further though but it was pretty tough to get to a mostly stable 50FPS on a system without fast RAM.

I will look into this... some time in the future. Don't hold your breath though, I really need a break after finishing this one
