Danger Zone Danger Zone is a 2 player air combat game, in the same vein as the flight games in Combat (Jets and Biplanes). Danger Zone is my homage to Atari's Combat and is a 48KB ROM with POKEY tunes @$450 (Supported in Dragonfly, not supported yet in Concerto). Controls: In the Menus : UP & DOWN to Navigate. Button 1 to select, Button 2 = back In game : Left = rotate anti-clockwise, Right rotate clockwise, Up = Speed up, Down = slow down, Button 1 = shoot. Features in the full game: 3 aircraft to take in to the Danger Zone: F16 Falcon MiG 21 Fishbed Eurofighter Typhoon Multiple & configurable colour & camouflage combinations for each aircraft (F16 & Typhoon have 36 colour combinations - each, MiG has 6) Multiple gameplay options that can be used individually or together Game Type - Timed (3 options), Scored (3 options) Clouds (on off number speed) Fuel (unlimited, limited) Ammo (unlimited, limited) Gun Range (long, short) Guided Ammo (on, off) Bullet wrap on screen edge (on, off) Time of Day (Day, Night, Sunset). To-do: Nothing! Special Thanks: @Synthpopalooza for some seriously superb POKEY tunes! @Trebor, @sramirez2008 & @-^CrossBow^- for providing invaluable feedback and testing and helping to find all the little bugs and issues. @mksmith for generously providing POKEY playback code - thanks mate @RevEng for general 7800 code guru duties and answering all of my questions, thanks Mike! @ZeroPage Homebrew for also finding a few elusive bugs (live on air!) and featuring Danger Zone on the ZPH stream. Demo: Demo is available and attached or can be played directly : Demo Link to JS7800 (click the JS7800 window after you click the link to give focus to the emulator or you don't hear the music until you do). The demo is NTSC only and is restricted compared to the full version. In the demo you cannot change aircraft and you cannot change the time of day or game type. All other options are available. Under emulation, it works in JS7800 (Pokey sounds fine), A7800 (Pokey sounds off) BupSystem (pokey a little off). It will run on various SD solutions such as Mateos carts (no Pokey?), Concerto (no Pokey on 48KB currently) & Dragonfly. Danger Zone RC4 NTSC demo.a78

Yes especially as my new 7800 is getting some TLC this week with a full maintenance rip down, UAV, Recap, Power supply change etc. Will be really good to do some testing of my own on real hardware, not that I don't appreciate the community testing (you guys rock!)- there will always be test release demos coming

Updated the first post with a link to the latest demo download as it was getting a bit cluttered.

I use memset in EXO and I've had problems with blackscreens but only under emulation, not real hardware. On real hardware the problem doesn't seem to manifest.

I really don't think they are the same. ah, @DrVenkman explained it more clearly than I did. While PokeyMax is available with an extended feature set that the 7800 does not need or use (PSG, SID, COVOX etc), the basic mono version of PokeyMAX, which is a completely separate product to PokeyOne, could indeed be used (or as pointed out, the stereo+covox version being the same price would work identically).

Thanks guys, I was taking a break from EXO the other night and I was looking at a project that specifically has an iconic death SFX and I wanted to know if it could be done on the 7800. I'm not the most clued up person when it comes to SFX and Music. It seems that it could be done going to park it in the "interesting projects box" for now and maybe I'll revisit that another time, once I've finished EXO and Danger Zone.

Looks great so far @vhzc 🕹️

I don't think that I have it backwards. I said there is a basic version of POKEYMAX. Here it is in the Dragonfly 7800SD cart : There are versions of this with larger more feature rich cores that include Quad Pokey, PSG / SID / covox etc. but there is also a version that's just a plain old Pokey. Different flavours that are available : I see no mention of "PokeyOne" anywhere there so it's a different product and as I said, "the basic version of PokeyMax" is an option.

I think there is also the basic version of POKEYMAX.

HOKEY is a POKEY replacement from reading @batari's posts. There are two original commercial games that used Pokey (Commando & Ball Blazer), so other than those, yes I'd expect ROMs would work. There are a bunch of homebrews that use Pokey, some work without but are enhanced with it present. Not sure about ROM availability on any of those.

good stuff You are quite right, the syntax is that you use to plotmapfile has to reference the file and the location in memory where you memcopy'd it to. If you are using a bankswitching scheme - the nice thing with this approach is that you can plotmap from a different bank and go back to the bank where the actual tiles are stored to draw the screen, meaning you don't have to try to cram all of your maps into one bank.

I believe you can, I do something similar to this in EXO to determine collisions with between the "front" of the playfield while ignoring the "deep background" tiles. I also use pokechar to RAM to animate a few things from tiles like the little tv screens in EXO. I might be wrong but I don't see any reason why you couldn't use tiles for collectables. [edit] - I'm also using Tiled for all of my screens.

Little update on Alpha 12. The code is now very stable and I've had no unexpected crashes. Thanks again to the folks testing and providing feedback that helped to squish bugs and issues and fine tune the features and difficulty. New stuff for Alpha 12, well there is a fair bit. Added a few bits of cosmetic fluff. I love nice presentation so I've been polishing that up a bit. World select screen. When you launch you get to choose where to go. Worlds 1-3 can be chosen, World 4 is locked until you complete those 3. Added some secret areas, reading the room names can help Added an artifact to each World. You don't have to collect them, but well, folks like hidden things right ? collecting hidden things usually does things ..Secret things.. Added rocket crates and extra life pickups, not many, don't want to spoil folks. Added some cinematics for launching, landing, entering the world that you selected. All skipable in the final code for those impatient souls I'll drop a new demo soon, probably won't be Mateos compatible. Stuff I'm working on for the next build: Well this next built will be quite a big step as it's integrating all of code path stuff for World 2 and 3 and the level structures (about 50 screens). In the pipeline : World 2 & 3 integration. I'm also working on the GFX for world 4, they are about 50% done. I've also reworked the enemy sprites on World 1. EXO originally started as a Cybernoid port but moved on to become it's own thing so it's time to retire them and use the new sprites I've built which fit the theme of each world better (Tunnels, Factory, Temple and so on). New title page is in progress Improving the cutscenes at the end of each world and improving the linkage and story flow. Adding a pause screen that's also a status screen. Further down the line : tweaking the engine code for World 2 and 3 to add unique challenges consistent with those worlds

The why doesn't matter, it's damn cool

That's a great analogy and is pretty much where my own evolution led starting with Tyre Trax, Dare Devil and onwards to the 7800, where, with more resources, you can have more levers and complexity

Thanks Trebor !

Would it be possible to play a sample sound on the 7800 via stock hardware, or via Pokey/XM ? I'm thinking just 1 or 2 simple short sounds. Would it be too processor intensive?

can you link your code?

I mentioned 4, Dragonfly, Saint, Concerto, Concertino = 4 options.

I'm not sure how Dragonfly cost will be cost prohibitive, unless I'm missing something. It's $93 Dragonfly vs $99 for Concerto. Maybe with shipping to the US it Dragonfly would be less competitive (the same is true in reverse shipping stuff from the US to folks in Europe, that's usually a stinger for me), or adding the options for Pokey and Yamaha, but then that's the same for Concerto too I expect. (Pokey, not Yamaha). Compatibility for all carts probably remains to be seen across the spectrum of 7800's, NTSC boxes included, but I hope all of them get to market and fulfil the feature sets being touted, that way there is likely something for everyone's taste, requirement, desire and budget. I don't think it needs to be a partisan discussion. I think this is a fantastic time, maybe even a golden age for the 7800. There are so many developers active now, mature tools like the fantastic 7800Basic and now not 1 but potentially 4 SD cards solutions coming to market that will aid developers and support consumers alike. I just wish that they were here already!

Good old eBay

Looking for a UAV for my (soon to be purchased) 7800. I just checked and unfortunately they are sold out on Rees's website. I notice that you sell them through eBay. Would offering the global shipping program option be a problem? that way folks would pay the shipping and any duty upfront and prevent local orgs like Royal Mail gouging their handling fee and screwing up the VAT charges. It's not ideal but it removes some of the hassle.

Has to be red, surely. Everyone knows that red goes faster

Fantastic work

same please take my money!
