Created with GIMP

For these that play games on consoles, acquiring titles that had been compatible has usually been simple. You choose it up, take it dwelling, insert media and play. No matter what the era, computer system games can in some cases be a hassle. You have to have a technique that meets particular technique specifications, such as processors, RAM, add on cards and so forth. Back in 1992, a port of the game “Another World”, which had been released the prior year, was released for the Apple IIGS, but was not compatible with the original Apple II series. Rapidly forward to 2019, and the classic Apple II models are ultimately going to be having their personal port of the game, thanks to a new homebrew.

“Another World” is the story of Lester Knight Chaykin: A young scientist hurtled via space and time by a nuclear experiment gone incorrect. In an alien and inhospitable globe, you ought to dodge, outwit, and overcome the host of alien monsters, when surviving an atmosphere as deadly as your enemies. More than the years, “Another World” has attained cult status amongst critics and sophisticated gamers alike.


“Another World” (a.k.a. “Out of This World” in North America and “Outer World” in Japan), was initially created for the Commodore Amiga and Atari ST computer system platforms by Delphine Application in 1991, “Another World” would later be ported to other computer systems of the era, such as the Apple IIGS and DOS primarily based PCs. In the console globe, it would see a release on the Super NES, Sega Genesis and 3DO all through the early to mid 1990s. Additional not too long ago, the title has been released on contemporary consoles and mobile devices, spawning an independent homebrew port for the Atari Jaguar a couple of years ago, and a Sega Dreamcast port final year year.

The Apple IIGS was very first introduced back in 1986 as an updated and enhanced model of the series, boosting a 16-bit infrastructure, larger high-quality graphics and sound, and a graphical user interface. For the duration of the very first year of sales, it sold far better than any other Apple item, such as the Macintosh. The stories and legends state that the IIGS clock speed was intentionally restricted so the technique would not outperform the Macintosh series, regardless of getting a enormous update to the classic Apple II line that was promoting quite properly. Some members of the corporation wanted the Apple II to die, so they could concentrate on the Mac lineup, but the Apple II did not leave with no a fight. The IIGS would be discontinued in December of 1992, when the IIe, which was very first released in January of 1983, would attain the finish of the road in November of 1993.

The Apple IIGS version of the game was rather exciting in a weird sense, when you assume about the original eight-bit models continued for nearly a year soon after the 16-bit IIGS was taken off the industry. Back in 1992, if you wanted to play a copy of “Another World”, you necessary to have the updated technique. If you had any other model, you had been just out of luck, which is exactly where this function in progress port enters the image.


The new port comes to us from Deater of VMW Application, who has produced the project by working with a 6502 assembler from scratch, and only working with the original Apple IIGS release as a reference point. The main troubles that come with downgrading a game from the IIGS to a regular Apple II, involve the graphical resolutions, along of the quantity of accessible RAM, in attempts to make the game compatible with all Apple II models, going back to the original a single that was very first presented back in 1977.

Going to the graphics mode for a moment, the Apple IIGS presented a 320×200 resolution, which for games on that computer system model was quite impressive. That is compared to the low resolution graphics mode that is getting made use of on the port, which is only 40×48. In his FAQ file for the project, he talks about his function on the graphics:

“I spent a lot of time as an ANSI artist so I am made use of to blocky 16-colour graphics, and to be sincere with you my art expertise sort of peak at that resolution. Also Apple II graphics programming is painful and LORES is so considerably simpler than HIRES (it is also smaller sized, more quickly, and requires significantly less important RAM). Partly nostalgia also, but my family members only had a monochrome monitor so I by no means got to expertise complete-colour LORES back in the day. However this game does not genuinely play properly in monochrome. Though not as poor as Hires, double-LORES is also a discomfort.  It only performs on the IIe with 128k or newer.  Also you now have to copy points to aux memory, and your sprites have to be concerned about the colors getting shifted (I assume) on the AUX web page.  It will take twice the ram and possibly run 1/two the speed.”


Going to the accessible RAM, Deater aimed to make the upcoming port as compatible as feasible with as a lot of models of the Apple II as feasible, and is arranging on cramming the complete game in code that will function with only 48k of RAM. In comparison, the Apple IIGS version expected 1MB of RAM. To make sure compatibility, he has also had to make some adjustments that had been particular to the original two models of the Apple II. (As a individual that owned an Apple II+ computer system back in the day, I know these limitations all also properly.) He brings some of these limitations up in his FAQ file as properly, exactly where the keyboard brought up some troubles on earlier models:

“There’s a thing about programming on a machine from 1977, whose graphics hardware is a glorified shift register, and is implemented completely out of 7400 series logic and 555 timers. The Apple II/II+ only supported uppercase letters by default. Also no “|” character, which explains why some of the ASCII art appears a bit odd… In theory, [you could use this on an original Apple II from 1977].  You would have necessary a 48k model which would have been costly at the time ($2638).  Also the disk image will fail to auto-boot and HELLO will not run as it is in Applesoft Standard (not the Integer Standard that came with the original II). You will have to manually sort C600G and then POKE ,1 or two to address five (to choose intro, level1 or level2) and then “BRUN LOADER” [to get it to start…] The Apple II has simplistic keyboard assistance.  In common it is not feasible to study extra than a single important at a time.  Also on pre-IIe machines it is not genuinely feasible to get important-release events.  In addition, on older models there’s no auto-repeat unless you hold down the REPT important, which tends to make operating challenging.  The original game genuinely depends on getting capable to detect getting several keys down at when.”

At the moment, this eight-bit Apple II port of “Another World” is a function in progress, and as such, there are nevertheless some pieces that want to be implemented into the supply code, and there are some recognized bugs in the game that nevertheless want to be squashed. The most present version of the game (v2.7) is accessible to download as a cost-free disk image, that can be made use of on your favored Apple II emulator. Physical floppies can be created working with a plan such as “ADT Pro”. To run the game on actual hardware, you can use any model Apple II. (It has been tested effectively on the II, II+ and IIe models, but has not been tested on the IIc, IIc+ or IIGS.) You want a technique with 48k of RAM, and in order to hear music in the course of the finish credits, you want a Mockingboard Card in Slot four. There is no word on when the game would be 100% completed, and no word on if cost-free distribution would nevertheless be presented when the game is finalized.
