Tempest Posted August 7, 2012 Share Posted August 7, 2012 So do Los Angeles Games and Innerspace only have title screen differences? I would assume yes? Elf Adventure looks interesting. I've never heard of this one before. Almost looks like a homebrew hack of Adventure. Quote Link to comment Share on other sites More sharing options...
Wickeycolumbus Posted August 7, 2012 Share Posted August 7, 2012 Very cool of him to release these! Anyone else having trouble with Elf Adventure? It doesn't seem to work in Stella 3.5.5. Quote Link to comment Share on other sites More sharing options...
Tempest Posted August 7, 2012 Share Posted August 7, 2012 Two questions: 1. Was Track and Field ever released in PAL format before this prototype? 2. Does the NTSC version display the alternate title if plugged into a PAL machine like the Atari 8-bit version does? Quote Link to comment Share on other sites More sharing options...
Wickeycolumbus Posted August 7, 2012 Share Posted August 7, 2012 While I haven't checked, I doubt the NTSC version would display a different title screen on a PAL console. There isn't really a way for the program to check the console type. Quote Link to comment Share on other sites More sharing options...
Rom Hunter Posted August 7, 2012 Author Share Posted August 7, 2012 (edited) Two questions: 1. Was Track and Field ever released in PAL format before this prototype? 2. Does the NTSC version display the alternate title if plugged into a PAL machine like the Atari 8-bit version does? 1. No, Los Angeles 1984 Games was to be the European release of Track & Field. 2. Nope. Innerspace has different in-play graphics (the spaceship and radar stations are different). IMO Imagic should have kept the original graphics and game title. Innerspace sounds much cooler than Laser Gates. Edited August 7, 2012 by Rom Hunter Quote Link to comment Share on other sites More sharing options...

edweird13 Posted August 9, 2012 Share Posted August 9, 2012 No one else is having problems with Elf Adventure? Won't load at all for me. I can't get it to work either. I have tried all the different bank switching with no luck. Quote Link to comment Share on other sites More sharing options...
Rom Hunter Posted August 9, 2012 Author Share Posted August 9, 2012 Indeed, Stella doesn't accept it. But Z26 does on my PC. Quote Link to comment Share on other sites More sharing options...
Eckhard Stolberg Posted August 9, 2012 Share Posted August 9, 2012 (edited) Indeed, Stella doesn't accept it. But Z26 does on my PC. The reason for the difference is that Stella randomizes the RIOT RAM, while z26 sets it all to zero. The game only initializes certain parts of the RAM and accidentally relies on the rest to be zero. Therefore it might not work on a real VCS either. Elf Adventure has a routine where it copies the address for an indirect jump from a ROM table to RAM. It reads the index into this table from one of the uninitialized RAM addresses. Therefore the index is incorrect in Stella most of the time, so when the game does the jump it ends up in the wrong code and crashes.

+Gemintronic Posted August 9, 2012 Share Posted August 9, 2012 Digital Press mentions that a design document exists for Elf Adventure. I can't find any links to it though. http://guide.digitpress.com:8080/DP/cmf/game.cmf?gameid=48705 Quote Link to comment Share on other sites More sharing options...

Rom Hunter Posted August 9, 2012 Author Share Posted August 9, 2012 Here's another one for you: http://www.atarimania.com/game-atari-2600-vcs-golf-diagnostic_28557.html Again donated by Scott Stilphen. Quote Link to comment Share on other sites More sharing options...
Tempest Posted August 9, 2012 Share Posted August 9, 2012 Neat! Does the equipment to make it work exist as well? Quote Link to comment Share on other sites More sharing options...
Wickeycolumbus Posted August 9, 2012 Share Posted August 9, 2012 Very cool to see stuff like this get released Indeed, Stella doesn't accept it. But Z26 does on my PC. Thanks, works for me now too. Quote Link to comment Share on other sites More sharing options...
+stephena Posted August 9, 2012 Share Posted August 9, 2012 Stella has a commandline argument called 'ramrandom' which fixes this. Setting it to 1 randomizes (the default), setting to 0 makes the RIOT RAM contain all zeroes. Unfortunately this isn't accessible from the UI; you need to launch from the commandline or edit the config file directly to change it. Incidentally, the reason this is a setting is that different consoles have different behaviour. My two test systems in particular (light sixer and vader) both seem to randomize RAM. EDIT: I don't recall when I added this, so I don't know if it's in 3.5.5. I suggest upgrading to the latest version (3.7.2). Quote Link to comment Share on other sites More sharing options...
Omegamatrix Posted August 10, 2012 Share Posted August 10, 2012 All of my consoles had randomized ram too, so this rom will crash most of the time in real hardware. I'm not sure what it will do in Harmony cart in multi-game mode because I haven't tried, but I do know the RIOT ram is fixed when using the Harmony cart like that. Still hoping one day for 7800 detection with the Harmony, but its been a long, long time... Incidentally, I found the Colecovision 2600 adapter always had the RIOT ram initialized to all zeros.

Tempest Posted August 10, 2012 Share Posted August 10, 2012 Have the roms for all those 3-D Amiga games been released yet? I thought they were going to release the roms once the repros sold out. I assume this hasn't happened yet? 2 Quote Link to comment Share on other sites More sharing options...
Nukey Shay Posted September 22, 2012 Share Posted September 22, 2012 Elf Adventure is easily fixed by just adding a cold start loop (6 bytes). Removing a couple of unneeded JMP's covers that. Now can somebody tell me what this thing is supposed to be doing? ElfHack.bin Elf.asm 2 Quote Link to comment Share on other sites More sharing options...
Gateway Posted October 2, 2012 Share Posted October 2, 2012 Weird. Only seems to be about 5 or 6 rooms and no collision detection yet. Quote Link to comment Share on other sites More sharing options...
Tempest Posted October 2, 2012 Share Posted October 2, 2012 Supposedly there are several versions but I think this is the only one that has been released. I need to look into this one and add it to my page. Quote Link to comment Share on other sites More sharing options...
Nukey Shay Posted October 3, 2012 Share Posted October 3, 2012 Collisions work fine from what I see. You can steal objects that the two "faces" carry above them (and they chase and attack you to get the object back). I realise that everything is just placeholders - probably including the limited kingdom area - because this is easily expanded once the game engine is complete. I'm just trying to envision what the concept was going to be. Quote Link to comment Share on other sites More sharing options...
+bfstats Posted September 5, 2014 Share Posted September 5, 2014 Bumping an old thread, but I JUST discovered Elf Adventure. Thank you, Scott, for several more significant contributions. Thank you, Nukey, for the ROM fix. Tempest, it's not on your site. Did you ever "look into it"? Quote Link to comment Share on other sites More sharing options...
Tempest Posted September 5, 2014 Share Posted September 5, 2014 Tempest, it's not on your site. Did you ever "look into it"? Nope, sure didn't. In fact I totally forgot about it. I'll get to this eventually. Quote Link to comment Share on other sites More sharing options...
