Games galore #32: Inviyya II: Hyperblaster, Gunsmoke, Depthcharge, Blockman Gets, Flappadiddle

Autofire! Another round of catching up with Amiga game development.

Inviyya II : Hyperblaster

Great shoot-em-up game "Inviyya" by Tigerskunk is about to get a sequel: "Inviyya II: Hyperblaster" was announced in the first half of 2022, and updates on development progress have been posted on the internet since. 

"Hyperblaster" looks even better than its prequel, and interestingly a NeoGeo port is in the works, too. So far there's no sound in the Amiga version, but according to the author's YouTube channel, sound has just been added to the NeoGeo port - maybe the one we'll soon hear in the Amiga (CD32) version? Check out Tigerskunk's videos for more "Hyperblaster" previews!

Here's the latest work-in-progress video on Tigerskunk's YouTube channel (2022-10-01):


Erik "Earok" Hogan is working on an Amiga port of 1985 arcade game "Gun.Smoke", which is a vertically scrolling shoot-em-up similar to "Commando", but western-style. 

"Gun.Smoke" is one of the arcade titles that got ported to a lot of consoles and 8-bit platforms, but strangely never to the Amiga. Well, obviously this is about to change. The upcoming Amiga port is in early development stage, but a video posted on Twitter looks very promising.

Even deeper into the depths of retro computer gaming: The year is 1977, Gremlin Industries (later to become part of SEGA) releases "Depthcharge" to the arcades. It's quite a simple, but also quite an enjoyable game that wasn't the biggest hit ever, but good enough to produce a lot of clones and remakes for numerous platforms.

Fast-forward to 1994: An Amiga version of "Depthcharge" is released as pd/freeware. It looks beautiful, but different from the arcade version.

Fast-forward again to 2022: "Depthcharge" is being remade by AcidBottle. At version 0.2 it's far from finished, but it already plays nicely, and captures the feeling of the arcade original near-perfectly...

...Dive! Dive! Dive!

Here's a video from ISB's YouTube channel (2022-04-05):

Blockman Gets

So Pacman has a strategist brother that goes by the name of "Blockman". Nice. In this cute, slightly trippy game Blockman has to find a well-thought-out path through several mazes filled with pills, making sure he gets enough of them. 

Not only does that sound tasty, it's also addictive.

Finally for this issue, we have yet another neat little game by highly productive developer Jayenkai. "Flappadiddle", released in the second quarter of 2022, puts you in control of Flappy, a tiny yellow bird that has to avoid various obstacles on his way to the target platform, which transports him to the next level. The only protection he has are his flying abilities, and some intermediate landing platforms. 

So "Flappy Bird" meets "Space Taxi", kind of. It's a quick'n'clean production - graphics are simple but effective, sound is loud and quirky, it plays flawlessly, and the idea is a little stroke of genius. Great low-fi stuff!

AMIGA alive software: zx81paint 0.2

A new version of zx81paint has been uploaded to AmiNet.

zx81paint has just learned a couple of new things: 15 steps of undo, drawing lines and rectangles, better menu layout, and slightly improved keyboard control.

Lines! Rectangles!

Games galore #31: Duke Nukem 3D, Wolfenstein 3D: Spear of Destiny, Yoomp!, Wonderboy, Robocop AGA

OMG, it's been a long time since the previous issue - again we have a lot of catching up ahead: Huge names in this issue! First-person-shooters, arcade, movie tie-in!

New "Duke Nukem 3D" ports

This game certainly needs little introduction - "Duke Nukem 3D" set a new standard for first-person-shooter games for grown ups (and maybe not so grown ups). In the first half of 2022 two new Amiga ports surfaced.

One is "jfduke3d", which seems to be the slightly less resource-hungry of the two ports, and the other is an update of "AmiDuke". Both require a 68060 CPU, additional RAM, AGA chipset or RTG card, and some files from the original PC game. "AmiDuke" also requires AHI, and "jfduke3d" has TCP/IP multiplayer support (AmiTCP, Miami, Genesis, ...). See links below for more information.

New "Wolfenstein 3D: Spear of Destiny" ports

Very much like "Duke Nukem 3D", notorious first-person-shooter pioneer "Wolfenstein 3D: Spear of Destiny" has many incarnations and needs little introduction. Also much like "Duke...", two new ports for the Amiga have been released early this year.

Previously "AmiSpear" required an RTG card, now it's available for ECS and AGA equipped Amigas, too.

Just a couple of weeks later another great new port appeared on AmiNet, it's called "spear4amiga". This one seems to have the lowest system requirements: according to the AmiNet-readme, it runs on an unexpanded Amiga 1200. A little more horsepower is recommended, though.

Both ports require some game data files from the original PC version. See links below for more information.

"Yoomp!" might not be as well known as "Duke Nukem 3D" or "Wolfenstein", but it's still a big name: the game was created for the Atari XL, ported to Commodore 64, and there's a spin-off called "Jump!" for AGA Amigas that has certainly raised some eyebrows.

In Jan. 2022 a teaser of the original game of "Yoomp!" for OCS Amigas with 512KB RAM expansion was published. It looks a bit more retro than "Jump!" does on AGA, but it certainly doesn't fail to deliver on groovy music and colorful ball bouncing, eye popping arcade fun. A release date hasn't been set yet.

Here's a "Yoomp!" Amiga OCS preview video from Saberman's YouTube channel (2022-01-08):

Wonderboy 1200

SEGA's original "Wonder Boy" from 1986 is a great jump-and-run (or skate) arcade game that was a bit of a hype when it was converted for home computers around 1987, and it got a lot of positive reviews. Finally, only about 35 years late, it looks as if we get to play it on our Amigas.

Developer "acidbottle" is working on a remake, and the latest preview video gives the impression that it's close to completion. "Wonderboy 1200" looks and sounds just as enjoyable as the arcade original - if you're into tomahawk-wielding toddlers, snakes, spiders, humongous eggs, and skateboarding, then it's the perfect game for you!

Here's the latest preview video from Acidbottle 0101's YouTube channel (2022-07-13):

Robocop AGA (work-in-progress)

Daniel Allsopp is working on an AGA remake of 1988 arcade game "RoboCop" since 2021, and has been posting "development diary update" videos on YouTube, the latest of which is just a couple of days old. 

In stark contrast to the 1989 "RoboCop" game by Ocean, his remake looks totally AGA, and almost identical to the arcade original. No release date has been set yet, but if you watch a couple of Daniel's videos you'll see that a lot of work has already been done, and this is going to be a quality product. Awesome!

AADevLog #5 - Will it become... a game?!

Creating your first action game from scratch can be quite a challenge, and cause severe frustration. But at some point you begin to see some light at the end of the tunnel - and that's where the real fun part begins.

My experiments in creating something that might become... a game?! ...have reached a stage where (except for sound) pretty much everything is in place: timing, user input, movement, graphics, limits, ...and it seems to work! Stably!

To achieve this within a somewhat tolerable time frame (= this lifetime), some fundamental decisions had to be made: 

- few colors

It turns out that Amiga color palette considerations can be very time consuming. To make progress, no attempts were made to max out the possibilities.

- single reference platform support

AGA compatibility has been dropped early on, OS3.x would be nice, but Kickstart 1.x support is a must for this project anyway (for personal reasons), so an Amiga 500 with Kickstart 1.3, OCS, 1MB RAM has become the single target platform. If possible, the... game? ...should fit into 512KB RAM. (256KB would be even better.)

- accept bad performance now, optimize later

This is something I really had to get into my head: It won't be fast! Not yet! Maybe never! I have a tendency to spend a lot of time thinking about loops, variable size, etc. without being sure the entire program architecture will work out. (Compare AA DevLog #0.) So to get a proof-of-concept of where and when things happen, the basic assumption was made that with some fundamental limitations set, the Amiga will somehow be able to handle the load within one, or at least two vertical screen refresh cycles, resulting in a usable frame rate. All other performance- or elegance-of-execution-considerations were dropped.

Everything still looks pretty... flat.

Well, despite my self-imposed rules, I still tried to make some routines scalable, reasonably "elegant" (?), or spent a little bit of time on thinking about speed. It just happens, and is part of the fun.

Having an ugly, but working prototype of the game, a level editor speeds up further development considerably. Creating the editor was comparably easy, as many of the functions required were already there from the game files.

Editing an NPC's path/waypoints

Now background tiles, foreground items, and non-player-characters (NPCs) can be easily added to the level - and as mentioned in the introduction, this put a broad smile on my face a couple of times. It's really fun to invent game mechanics - e.g. a path with waypoints for your NPC - and then be able to immediately see the effects in the game.

Thanks for reading, c u next time!
