A tutorial to getting the most out of the Intellivision with Jzintv

@herb_fargus also as far as updating the wiki, i can fill in the needed extras. the only issue is that retropie really should use an emulators.cfg that matches what i have. it would completely eliminate that from needing to be in the wiki, then the only part that needs to be added is the part to make the picture quality look good and not all fuzzy and blurred.

i can get all the code i need, i just need to know what to do with it.

I've been looking into the script modules here and there and doing a bit of experimentation. I haven't got a full grasp on it yet, but at first blush it looks like it might be a simple matter of changing out the URL that wget is currently using.

edmaul69

@mediamogul can you tell me what the url is?

herb_fargus

@edmaul69 that's what I'd like to know. I can't seem to find the source, all I can find are the 64 bit Linux binaries. If the source can be located then we can work on fixing up the module for the latest build.

edmaul69

@herb_fargus ok well i know some people so i should be able to find it.

@edmaul69

You can usually find it next to a barber pole or circus tent. No, wait. I'm thinking of Waldo.

Can someone advise me if this seems like a sensible way of mapping my PS4 controller for Jzintv?

dudleydes

@hooperre YES! I would say that - they're my mappings. All I can suggest is to try them and see how it goes. If you're not happy, then feel free to adjust them to your liking.

Let me give an explanation of how I reached these configurations. The keyboard hackfile Arcade.kbd is the default one which I use for the majority of games where the disc on the Intellivision controller is mapped to the left analog stick on the PS3 controller, the action buttons to the face buttons, the keypad to the D-pad which you need to use with L1 and R1 to press keys 4 to 6 and keys 7 to 9 respectively. (It's called Arcade.kbd because it's the first keyboard hackfile I created for arcade style games such as Astro Smash and Lock'n'Chase. I just haven't bothered to change the name.)

This mapping makes it difficult to play games that require directional shooting such as Advanced Dungeons and Dragons:Cloudy Mountain and TRON Deadly Discs. For these, I created a mapping using xboxdrv and the keyboard hackfile hackfile.kbd so that the right analog stick can be used to shoot in the required direction, effectively making these twin-stick shooters. You can find an explanation of how this works here.

Other games that benefit from using xboxdrv are sports titles that require directional passing and shooting. These include:

Slam Dunk-Super Pro Basketball
Slap Shot-Super Pro Hockey
Spiker-Super Pro Volleyball

This mapping can be used for Night Stalker but I felt, as I only need to shoot in the four cardinal directions, it would be more precise to map shooting to the face buttons. To accomplish this, I created a keyboard hackfile Night Stalker (1982) (Mattel).int.kbd specifically for Night Stalker.

I also created specific keyboard hack files for games such as All-Star Major League Baseball where the right Intellivision controller needs to be used to play one player games and Dracula where the right controller is used to control the zombie (I've mapped this to the D-pad so it's possible to control Dracula and the zombie at the same time!). There are other titles for which I use specific mappings where I felt the default didn't work for me.

Each of these games would require a separate entry in /opt/retropie/configs/intellivision/emulators.cfg to account for the different keyboard hackfile flags in the launch command. Rather than do this, I created a script jzintv.sh which will launch games if it finds a keyboard hackfile with the same name as the rom with a .kbd extension.

As I said, give the mappings a try. I would suggest starting with the general mapping, Arcade.kbd before trying the other mappings. If there's any further info you need then let me know. If you would like copies of the keyboard hackfile for All-Star Major League Baseball, Dracula or other titles, then I'm happy to add them to the gist.

Ah awesome thanks for your response. As someone who hasn't used xboxdrv before... does it automatically override my configuration settings in ESconfig? Or does it specifically need to be called in the emulators.cfg?

dudleydes

@hooperre xboxdrv is only called when a game is launched in jzIntv. Just make sure to disable xboxdrv after you have installed it so that it's not continually running in the background. You can do this in Configuration/ Options in the xboxdrv installation menu in the RetroPie setup script. The xboxdrv process will be killed after you exit jzIntv so you will have default controls in ES.

You will also need to change this line in the xboxdrv configuration file intellivision.xboxdrv for the PS4 controller. Run the command ls /dev/input/by-id/ and look for the entry for your PS4 controller that includes event. Now replace usb-Sony_PLAYSTATION_R_3_Controller-event-joystick with the PS4 controller entry.

I'm going to start an issue on github for the inclusion of .rom in the es_systems.cfg, but I believe there might be a few more that need adding. Currently, .bin and .int are covered, but it seems as though .rom, .itv and perhaps even .cue should be there as well. Can you confirm this? Also, can .bin files be used without an accompanying .cue? If not, it may be that .bin needs to be eliminated from es_systems.cfg in favor of .cue as is done with the PSX and SegaCD entries.

edmaul69

@mediamogul .cue files accompany .int and .bin but never try to boot them. They arent like other .cue files. But yes if .rom .ROM isnt included then they should be. All mine are .rom files. .int can just be renamed to .bin. The pc version of jzintv comes with 2 programs. Bin2rom and rom2bin. These can convert them both ways. If you are doing bin2rom you need the .cue and .bin in the same folder as the program. There are maybe 2 prototype games that wont work trying to convert to .rom because of the code thats in the .cue file. Go for the gold is one of them. Drag the .bin or .rom onto the programs rom2bin and bin2rom. Dont drag the .cue file ever though.

mediamogul

@edmaul69

Just to cover all the bases, is there anything special about .itv, or is it just another iteration of .int/.bin?

edmaul69

@mediamogul i am not sure what a .itv is. I have never seen it. But it might just be a .bin renamed like .int.

edmaul69

@mediamogul when a .bin is renamed to .int it just keeps it from looking for a .cue file.

edmaul69

@mediamogul so it appears .itv is a nostalgia rom. I only use nostalgia to get the crc numbers to compare trying to find rom variants.

mediamogul

@edmaul69

Gotchya. It's listed as a format supported by jzintv, but that info is not coming from the main page. Do you have a ROM handy to confirm whether or not it'll launch. No rush of course.

edmaul69

@mediamogul when you say rom do you mean .rom or .itv?

mediamogul

@edmaul69

sorry, .itv.

edmaul69

@mediamogul i could not find an .itv rom anywhere however, i can tell you that joe states they work there is no doubt in my mind knowing joe personally that it works. He is a programmer for google and he is a phenomenal programmer.
