I really want someone to make a port of Spy Hunter for Intellivision. I figure it would play just as great as Bump'n'Jump and isn't overly graphic heavy so it would still look good on the old system. Not sure how well the music would transfer over though. Used to love playing it in the arcade as a kid.

Its certainly possible to do a version of it. You would probably end up up writing the automatic weapon fire, smoke and oil slicks directly into BACKTAB to conserve sprites. Then use two sprites on the player's car body colour and its wheels, leaving 6 sprites for enemies, bombs and enemy shots. The high speed scrolling could be done with just a BACKTAB card copy at the highest speed and pixel scrolling at the slowest speeds. I don't see a problem with the music, but it might have to go if there is a ton of stuff going on in the game with scrolling/AI and the like.

 

Edit: It would be a good game to do in foreground/background mode too.

Great stuff. Didn't expect to get an expert's take right away so thank you.

 

Do you think it would visually look good enough to hold up that what people are used to from this title in the arcade and on newer systems? Again I keep picturing it looking a lot like Bump'n'Jump, which I think looks great on the Intellivision.

No problem!

The Inty will never match the resolution and colour depth of the arcade machine, so you have to extract the elements of the game that are "fun" and implement those. In my mind, an Inty version would look and play much better than the 2600 version, and probably be close to the ColecoVision version visually. According to the arcade game's wiki entry the tune is played on one channel and the SFX on the other. We have 3 channels on the Inty so you could use one for the tune and two for effects.

 

At the end of the day I would rather see a fun SpyHunter-a-like game that plays to the Inty's strengths rather than a "perfect" port that makes the wrong compromises.

Agreed. I wasn't expecting it to look exactly like the arcade. Just good enough to be worthwhile on the Intellivision. The gameplay is far more important to get right, then look to keep as much of everything else as can be. That the music could be done is really cool. It always added to the feel of the game in the arcade and the NES.

Seems there is enough of a list of wanted titles that we could irritate another Eric for years to come.  :evil:  :mad:  :mad:  :mad:  :evil:

If it doesn't have Peter Gunn playing in the background, it's not really Spy Hunter. ;)

 

P.S. My favourite version is from Duane Eddy, "twangy guitar," surf rock legend! (Yeah, it's not all Italo Disco in my library...)

I can't promise you a game, but I can deliver a quick and dirty conversion of the C64 SID music. This is in IntyBASIC format, but it would not be awfully difficult to convert it to another tracker format if desired.

Attached File  spyhunter.bin   13.83KB   23 downloads
Attached File  spyhunter.bas   44.95KB   13 downloads

(Ok, it doesn't loop properly but I'll leave that as an exercise to the developer)

Sounds great!  It could use some refinement in the performance aspect, but it sounds cool.  :cool:

This is how refined you get within the ~15 minutes of work it took me to save SID to text, edit the data and compile. :-)

Oh, I didn't mean to diminish your effort.  I meant, if it were to be used on a port of SpyHunter, it could be polished some more.  It is very cool and impressive what you were able to do in just a few minutes. :)

No offense taken. I just wanted to boost the fact that even for a non-musician, there is a database of thousands (low count) songs in a mostly Intellivision (well, IntyBASIC in this case) friendly format waiting to be converted and inserted into people's programs, if nothing else than as a placeholder.

That's the best thing of all.  IntyBASIC has opened up the platform significantly. :)

 

Thanks for posting it. :thumbsup:

Yeah, unfortunately game code isn't as easy to convert, unless Decle can write an arcade, C64 or NES emulator running on the Intellivision...

Silly rabbit... programmers are for real games.  We're talking about a boxed cartridge for collectors here. :P

Even though this is one of my favorite arcade games, I don't think we need more arcade ports for the Intellivision, unless new features or new levels are added such as with Ms Pac.  I can already play all the old arcade games in MAME...

 

One of the big things that made the Intellivision great was the original complex, in-depth games, such as the AD&D games, B-17 Bomber, Sea Battle, Utopia, and Sub Hunt to name a few.  These games were a direct result of not having a bunch of arcade licenses.
