#4198180 Create and burn eproms for standard Jaguar 2 chip cartridges

Posted by omf on Tue Jan 15, 2019 4:57 PM


I have had a heck of a time finding the correct sockets for these boards, I keep smaller, up to 40pin, but nothing 42.    Does https://www.mouser.c.../XorZIrGZxBfeI=seem correct?


I've burned the posted sample, guess I'll try them after work on day this week and see if I can some success...

are you sure?



seems easy enough to me

They are not difficult to write, just code one up for your purposes, should take only 10-15 minutes to write from scratch in pretty much any native PC based language (C, C++, C#, PHP, Python, JAVA etc), choose your preferred language and just write it.


Ahh, you must mean one of these:

looks like the solder pads have been ripped off and the blobs are holding chips in the socket so they cant just fall out

#4074689 Risky Rick in Dangerous Traps (June 25th)

Posted by omf on Thu Jul 19, 2018 5:36 PM

i hope this statement does not include me!




i have also been subject to steeling asshats  see post 28 on page 2  hence i lost interest and have abandoned it for a while but do intend to go back at some point



I really wish some of you could go work on a game and know exactly what it takes to put together an entire game: the programming, the box art, the manual, shipping the game, etc, etc,  and then be dealing with a bunch of complaining assholes after you've done all that work to really know and understand just how frustrating it is to make something that should be "fun."

#4074151 Risky Rick in Dangerous Traps (June 25th)

Posted by omf on Thu Jul 19, 2018 5:59 AM

i am slightly struggling to understand how come there was possibly not very much testing of the game?  if it was tested on a un modified console then fair enough, in reality, the components inside the colecovision are so old i expect over 90% of the consoles that stil exists in working condition have been repaired in some fashion due to dead components.  if 5v video ram replace is the issue then there is some issue, this is one of the most common machine failures.


i dont really accept the fact that its just this game that doesnt work on specific consoles modded or not.  how come this has not risen its ugly head before in other games.

there is an issue with the F18a RGB board and PAL consoles but once that is removed and the vdp is replaced again (5v ram or stock it works fine).  if the F18a is attached to a NTSC machine it works fine on problematic games. this is known to be an interupt detection issue on the PAL boards


if the timeings are this sensitive the game needs rewriting sureley?



for the problematic screen for example:


if player x and y coordinates are between these specified values jump to the code that exits the screen and draw the next screen. (i beleive this problem screen is the final screen of this stage?)

and not wait for some timing event to happen that may or may not occur,  in my experience it does not occur :D ???


how come it loads all previous screens up to this point and not this last screen?



i am just throwing some ideas around at the moment because i dont appear to have a working (well enough) console to get past this screen

#4063666 Atari Jaguar joypad to colecovision converter

Posted by omf on Thu Jul 5, 2018 3:11 PM

with the results being populated above i have gained some extra enthusiasm for this project and worked on it somewhat this week.


that option (swapping colicovision and jaguar button mappin was implemented this week as 6 selectable options, 1 - 3 normal, 4 - 6 the same as 1 - 3 but reversed, this is selectabe by usng the jaguar option button

i also 90% implemented autofire.  need to add autofire speed selection and on and off as yet.  i will probably be looking at a bit bigger microcontroller with mre pins.   i have used all the io pins on a atmega328p, ill probably look at an atmega32 chip with 40 pins so i have a few extra pins


setting the autofire rate in the code to 100 milliseconds or there abouts and turning it on in the code works as it should on the joypad test program



upto 1400lines of code or there abouts, this doesnt include the debug function as its disabled on live builds anyway as i cant send data over the serial port as its needed for joypad reading and writing

#4015886 The truth about a certain individual and his slanderous accusations!

Posted by omf on Thu Apr 26, 2018 5:27 PM

I have become aware of a post by a certain individual on his own private Facebook group where only people are allowed to reside that agree with his ideals and beliefs.  If you disagree with his delusional mind even slightly than you are instantly banned from the group.


Hence I have been banned. 


So as I cannot voice my anger there, I am posting here, knowing full well that he will be informed soon enough by one of his delusional followers.


Attached File  Image2.jpg   220.37KB   24 downloads


This delusional individual is well known to spew countless lies on a range of subjects to suit his goals, in this case the slanderous accusation that I have sold copies of Battlesphere Gold at Jagfest UK, which is what is being referred to as 'at retro gaming events'.


For the record this is what actually happened:

I can’t remember the exact discussion due to it being many years ago, however the subject of BSG was being discussed, which went on to the subject of Thunderbird saying it was difficult and very expensive to make jaguar cartridges.   For whatever foolish reason, I chose to voice my correct opinion that it was a simple matter and relatively cheap to produce such a device.  With this said I demonstrated the fact using parts that I had at the show. 

This was back when painter was being produced and I sold a load to Nick Harlow at the show for him to sell in his shop so i had various parts there at the time.


There was only ever one of these made at the show on a socketed board I had pre prepared with sockets.  It was most definitely not sold to anyone and came back home with me after the show had finished.


Because I am so sure about this and what actually happened that day,  I invite anyone to post proof to the contrary,  without any hard feelings towards them in any way from me.  Why am I doing / asking this, well it is very simple. 

There is nothing to post because it did not happen.


This is not the first time this has been brought up on his questionable little group of delusional people over on Facebook.  Previous times I have let it slide because quite frankly I can’t be arsed with his delusional behavior and I have better things to do than attempt to fight this inaccurate slander, but as he insists on being a retard I am taking action to set the facts straight once and for all.



As he seems intent on accusing me of pirating and profiteering on BSG copies that I have apparently sold it seems only fair that I do the same with actual proof.


As everyone should be aware, there are still quite a few good people in the jaguar community and give away what they have made for free.  Looking at said delusional individuals ebay shop you can clearly see that he is attempting to make profit from selling free software.  If it was being sold as non profit I would expect the item price to be at the VERY MAXIMUM £2, 10p for a blank cd and a piece of a4 paper, some printer ink and a cheap cd case and possibly a small postage fee, but yet various peoples work they have given away for free is being sold for £24.99, that’s £23 profit going into this retards pocket

Don’t be stupid, download this stuff yourself and burn it yourself using JiFFI available here: http://reboot.atari..../jiffi_1.42.zip

A simple google search will reveal much of this stuff where you can download it for nothing yourself

For example, the creator of Jagmarble and Jagmania, Matthias Domin has kindly given away these games for free on his webpage, there IS NO NEED TO PAY FOR THEM, if you have paid for them you need to demand a refund from the person you bought them from.






So as far as I can see, this delusional individual accuses others of being a pirate, when he is actually a pirate himself and has no issues about selling other people’s work to make a quick buck at their expense.  I am 100% sure the authors of this software were not contacted for permission to sell their software.


All that is left to say is make your own mind up, don’t take sides based on one person’s point of view, make sure you do your own research if you are passionate about a particular subject.  Google is your friend, there is much information about peoples accomplishments and fails (some more than others), during your decision making process, you may want to look into what he and i have actually produced for the community, there will be a clear difference.


if you are siding with this persons lies, Great.

if you are siding with my account of the events, Great

Did this come out on a cart? Jag cd is a dieing breed.

yes indeed it did

#4015150 Will We Ever See a Re-Release of Painter?

Posted by omf on Wed Apr 25, 2018 4:07 PM

Its been 25 years since the original release of Painter on the Atari ST.

please do not let kieren hawken have easy acces to the community levels, he does not deserve them. 

i know this game has been discussed on his questionable facebook group that if you have another opinion to his you are intantly banned.


that being said all the best for whatever plans you have.

#4013337 Would this stepdown voltage converter work in the UK?

Posted by omf on Mon Apr 23, 2018 6:09 AM

no that would be a 3d print job which i could do for you i guess, the proper coleco plug is not manufactured any more.  the power supply i was mentioning was a din socket so would require a hole drilling in the case


the power supply part number is AP12UV-01

it outputs +5, +33 (not needed), +12, -5

ther does not appear to be any on ebay at the moment though but you will probably get one under £10 however, google it, ther are some pictures


it does 100 - 240 ac input so your good whatever voltage

#3919479 Importing backgound images

Posted by omf on Sun Dec 24, 2017 6:00 PM

@omf - in the beginning I tried but it immediately broke everything for some reason but that was when I very first started in the beginning and was ignorant to a lot of things so may have to give it another go

if you would like to give it another go, you can contact me directly for support. i don't mind helping people who actually use it :)

#3911762 The (RND*command questions x infinity<<16) Help Thread

Posted by omf on Thu Dec 14, 2017 2:53 AM

1, you would need to handle this yourself, i do not believe there is any functionality to do this automatically


2, you could probably add or subtract 1to the scale sections of the object list.  NOTE: scaling objects leaves the collision box as it is. you need to scale that separately.  use my list editor for the correct scaling values


3 you would need to control this manually, setting the gfxbase to the required address to the frame you want, there are a few examples of this going around, if you wan find any then i can provide something

#3859227 Atari JagDuo PCB discovered!

Posted by omf on Mon Oct 2, 2017 5:05 AM

Yeah, I'm not sure. The only problem with populating it is I don't think any remaining stock exists of the Tom and Jerry chips. Everything is still readily available for the most part.

as the netlists for those chips exist, it is theoretically possibly to create another batch of these


i have no idea how hard a task that would be or if the netlist files are the latest ones in existence either
