Homebrews on Atari 7800??

[ModerateNOOB]

Hi guys.

I'm having some trouble getting Atari 7800 homebrews to boot on any emulator i've tried?, At the moment i'm trying to get a homebrew game called Draker quest or Draker quest II to boot on Prosystem, Retroarch, Mess, Emu7800 or MAME.

 

No matter which one i chose, It won't boot the game. i noticed that it is much larger in size than other 7800 titles, Could it have anything to do with that?

Are you talking about the rom from this thread on the atari-age forums ? http://atariage.com/forums/topic/266146-draker-quest-2-wip/

If so I tested it with A7800, the modified Mame emulator specifically for the  7800 and it loaded up fine. http://atariage.com/forums/topic/268458-a7800-the-atari-7800-emulator/?hl=+a7800

So you simply had to use the only emu i hadn't tried, Yes it works with A7800 ?

 

Could i ask you for a little guidance on how to set it up with Launchbox?, I'm having problems with getting MAME to work on Launchbox (for a while actually).

Are there some special setting i need to make?, I can boot games from MAME if i go through the directories and do it manually, But doing the ordinary set up with Launchbox it's not loading anything.

 

Thank's for replying.

Yeah setting up the A7800 variant or Mame to work in LB took a little effort on my end because of how Trebor put it together.

Here is my setup for it, it includes everything you need including the high score and xm rom files, all you need to do is edit the a7800.ini file to add the path to your roms.

rompath                   "roms;D:\Emulation\NoFiller\NoFiller Atari 7800"

Above is mine for example, just change the part after the semi colon to your path.

In LB you will want the following command line in your associated platforms tab:

a7800 -cart1 xm -cart2

This will tell it to use the xm cart which is required for some homebrews.

A7800.7z

Hmmm, I still can't get it to work

I changed the rompath in a7800.ini to this 

which is the path to my 7800 games in Launchbox

we are not talking about bios files, Are we??

Of course i also pasted the command as you said.

 

[Lordmonkus]

Put quotes around your rompath like I have shown above, you have a space in between Atari and 7800 so quotes are required.

[ModerateNOOB]

Allrighty, I'm not so much into ini file configurations.

But it dosn't work.

And the command line.

But now i get 2 black windows that briefly pops up instead of 1, When trying to launch the game from Launchbox.

[Lordmonkus]

Double check that your rompath is correct and that is where your rom files are located on your system.

Also it could be possible your system doesn't like bgfx. Look for the video    bgfx section of the ini and change it to auto and save it.

[ModerateNOOB]

Thank's for all your inputs, But it will simply not work ?????

It was already set to auto, Only difference was that window was set to 1 instead of 0 (changing it didn't do anything).

The rom path should be flawless as it's copied directly from the end directory where the games are located (can't see anything missing)

Have all my emulation stuff on the same external HDD.

Is there any way to read that message that briefly pops up when trying to launch a game from Launchbox??, It says something (But what???)

[Lordmonkus]

You could try running it from the command line.

[neil9000]

In your mame ini is your rom path supposed to have a capital B in Launchbox? Mine is a lower case b.

[ModerateNOOB]

Sorry if it sounds stupid.

But what do you exactly mean??

If you mean directly from A7800 itself, It works just fine.

Yes the capitol B is present in my game directory and also in the rompath in the ini.

[ModerateNOOB]

Games which are not Homebrews runs just fine (with other emulators).

A7800 won't run anything.

I've been stuck with this weird MAME problem for months (pretty frustrating)

Check your main Edit Emulator window tab, maybe you got something there wrong.

[ModerateNOOB]

Ha ha ha, Yes that would be funny in a very stupid way.

I can't anything wrong, I must have checked the location of the A7800 exe file 150 times (just to make sure)

I'm so low on ideas that i even checked my anti virus.

[ModerateNOOB]

Okay, Just to make sure i didn't screw anything up.

This is the A7800 ini file before i made any changes.

And this is after i made changes, Is this correct??

[Lordmonkus]

All I can say is are your roms in that folder ? Is your platform name correct in the associated platforms window ? And did you change your games to use the A7800 emulator using the bulk edit tool ?

[ModerateNOOB]

I haven't used the bulk editor as i'm using different emulators to emulate as many games as possible, Prosystem and retroarch are managing most of my games.

I'm stuck at this Draker quest game which apparently only works with MAME/A7800

yes my roms are impoted to the Launchbox folder on my external HDD with the drive letter I:/Launcbox/Games/Atari 7800 , And the associated platform is Atari 7800.

I don't get it, But thank's a lot anyway.
