What is your top 10 list of Atari 400 or 800 games that you would want to see ported to the 5200?

Recommended Posts

As the 5200 do not have a plethora of scrolling man/platformer action games, - if this could be ported I’d think it looks like a nice addition:

 

 

 

Here is longer video showing more landscape and more enemies.

It seems Schrecenstein was produced for the Atari 800.

 

Is it then possible to port to the 5200 console?

 

From a screenshot it seems a Rom download takes 33-34 Kb.

 

Can different 5200 carts handle this?

@Albert

What would be the possibility of any of these games to be put onto the 5200?

 

if the 5200 is not capable, could some of these be ported to the 7800, say in a collection, or would the hardware be incompatible?

 

Do you know?

Or this!!

 

 

This would be amazing. I think extra RAM would need to be added to the cart for it to work.

I think the RAM problem is very complex or highly technical.

 

I wonder if ports of these games could be done using 16kB RAM, by shortening the games considerably.

 

Lets take a hypothetical example:

 

A game with 8 levels, is cut down to 4 levels.

 

A game with 8 different enemies per level, is cut to only 4 different enemies per level.

 

Something in that vein.

Although I have no idea regarding the technical issues involved with porting this over to the 5200.  Even if it could be ported over - which I doubt?  It's still less than a perfect platform game - in that I felt it wasn't the best in responsiveness and control.

The difficulty in porting - would be the same as for Space Harrier to be ported.  These were not designed with 5200 limitations in mind.

 

You're fortunate to have Bosconian ported over to the 5200 - by it's developer.

Some games can but it takes a heck of an amount of work to get to point where you'll know.

Two that I'd looked into for 5200 ports that would need more than the 16K RAM were Zybex and Lode Runner.

Then again, some can surprise you, Rampage was an example of that.

I hope Bosconian will be put on Carts (and perhaps even neat boxes 🙂 ) and become available here and elsewhere.

RAMpackRAM expansion cartridgeRAM expansion unit (REU),[3]memory expansion pak[4] and memory module[5] are some of the most common names given to various self-contained units or cartridges that expand a computer, games console or other device's own internal RAMin a user-friendly manner.

Such units are generally designed to be installable by an end-user with little technical knowledge, often simply by plugging them into an expansion or cartridge slot easily accessible at the rear of the machine (e.g. the Sinclair ZX81 or the VTech Laser 200[6][circular reference]), or via a user-accessible hatch (e.g. the Atari 800's CX852 and CX853 modules or the Nintendo 64 Expansion Pak[7]).

The ZX81 16K RAM expansion gained particular notoriety for the "RAM pack wobble" problem[8][9] because it was top-heavy and only supported by the edge connector. This could lead to it falling out, crashing the ZX81 and losing any program or data currently in the computer's memory.

Examples of such memory expansions include:

A RAM pack?  Well, supposedly the 5200's Expansion Slot doesn't have the bandwidth to do anything cool like RAM expansion. I suspect what needs to be accomplished is a plug-in expansion board like the rather limited-edition XBoard for the 7800, but for the Mighty 5200. The XBoard plugged into the MARIA chip's socket on the 7800's motherboard and provided 128K RAM and Dual POKEY sound chips. What essentially doomed the XBoard was that very few 7800's had socketed MARIA chips and despite how popular it is to do AV Upgrade Mods on the 7800 requiring soldering, this was deemed by many to be impractical for the XBoard.

 

Now, how many 5200's have socketed chips compared to the 7800? Lots. Many. Maybe all of them. So the key would be to find a perfect candidate chip, maybe even the SALLY CPU, plug in such a hypothetical expansion board to it, and then standardize on supporting whatever address the RAM is mapped to. Would a new BIOS have to be coded? I don't have an answer for that. But I would say that 128K RAM should be the bare minimum in such a hypothetical upgrade since RAM - even SRAM - is cheap and then the 5200 could run something like the A8 version of Stunt Car Racer which uses a full 128K to run the C64 code on A8 hardware. That, demos, and anything else developers might want to throw at it. Personally, I'd say go for 1MB so the 5200 would have memory equal to the popular Ultimate 1MB Upgrade on A8. Now even with that, the 5200 still wouldn't have SIO or light gun capabilities like A8 and the 7800 with an XM but it would substantially improve possibilities such as the bare minimum of porting A8 games requiring more than 16K and without having to aggressively modify bankswitching routines to make up for the lack of standard RAM and the difficulty of using cart-based RAM with the 5200.
