Original Post

I spent a great deal of time trying to figure out how to create 7800basic compatible graphics with my first game, so I thought I'd share the steps I took to make it work. Using Gimp is the easiest way to get started (you can download it here).

 

First, open a 7800basic palette file, which you can download here.

Open Palette

Next, click on Windows->Dockable Dialogs->Palettes, we need the Palettes dialog box to be open.

 
Palettes

Next, right click on the Palettes dialog box and click Import Palette.

 
Import Palette

Once the window is open, click on Image, Palette name (rename to Atari7800), and click on Import.

 
Rename

Click on Image->Mode->Indexed.

Indexed

Click on Generate Optimum Palette and change the number to 13, then click on Convert.

13

Change setting back to RGB, just so we can go back and change it to Indexed again to make one more modification…

RGB

Click on Image->Mode->Indexed again to make one more change.

Indexed

Click on Use custom palette, then the button next to it.

Use Custom Palette

Click on the 7800palette that was just added, then Convert.

Convert

Click on open image, and open the tileset_rocks image from one of RevEng's samples in the distribution.

Open Image

Click on View->Zoom->800% so you can actually see the image on the screen.

Zoom

Resize the window so you can see the entire image.

Resize

Click on Windows->Dockable Dialogs->Brushes (we need the brushes dialog box open).

 
Brushes

Change brush size to 1.0. Go to Windows Menu->Toolbox or press CTRL+B to open the Toolbox Tool Options if you don't see it on screen.

 
Toolbox

Click on color picker tool and choose one of the four colors to modify the image. The colors in this image don't matter yet, as they are changeable with the PxCx command in the code. One of the colors is transparent and will take the background color.

 
Color Picker Tool

Click on the brush tool to change the image.

 
Brush

Use the brush tool to modify a 16x16 area, there are three side by side in the samples from RevEng, each is 16 pixels across. Don't worry about the colors, as they are set with the PxCx commands in software. You can use the same colors in the sample images.

16 x 16

When you're done, click on File->Export As to save.

Export

Export the image as a PNG file and you're ready to go.

In Case You Didn’t Know

 

B Vitamins = Good

Some people appear to have a mental illness because they have a vitamin B deficiency. For example, the wife of a guy I used to chat with online had severe mood swings which seemed to be caused by food allergies or intolerances. She would became irrational, obnoxious, throw tantrums, and generally act like she had a mental illness. The horrid behavior stopped after she started taking a vitamin B complex. I’ve been taking #ad Jarrow B-Right for many years. It makes me much easier to live with.

 

 

Soy = Bad

Unfermented soy is bad! “When she stopped eating soy, the mental problems went away.” Fermented soy doesn’t bother me, but the various versions of unfermented soy (soy flour, soybean oil, and so on) that are used in all kinds of products these days causes a negative mental health reaction in me that a vitamin B complex can’t tame. The sinister encroachment of soy has made the careful reading of ingredients a necessity.

 

 

Wheat = Bad

If you are overweight, have type II diabetes, or are worried about the condition of your heart, check out the videos by William Davis and Ivor Cummins. It seems that most people should avoid wheat, not just those who have a wheat allergy or celiac disease. Check out these books: #ad Undoctored, #ad Wheat Belly, and #ad Eat Rich, Live Long.

 

 

Negative Ions = Good

Negative ions are good for us. You might want to avoid positive ion generators and ozone generators. Whenever I need a new air cleaner (with negative ion generator), I buy it from surroundair.com. A plain old air cleaner is better than nothing, but one that produces negative ions makes the air in a room fresher and easier for me to breathe. It also helps to brighten my mood.

 

 

Litterbugs = Bad

Never litter. Toss it in the trash or take it home. Do not throw it on the ground. Also remember that good people clean up after themselves at home, out in public, at a campsite and so on. Leave it better than you found it.

 

 

Climate Change Cash Grab = Bad

Seems like more people than ever finally care about water, land, and air pollution, but the climate change cash grab scam is designed to put more of your money into the bank accounts of greedy politicians. Those power-hungry schemers try to trick us with bad data and lies about overpopulation while pretending to be caring do-gooders. Trying to eliminate pollution is a good thing, but the carbon footprint of the average law-abiding human right now is actually making the planet greener instead of killing it.

Hydrofracking = Bad

Hydrofracking is bad for you, your family, your friends, and the environment.

 

 

Hydroxychloroquine = Good

Although some people with certain conditions may not be able to take it, hydroxychloroquine is a cheap drug that has been prescribed by doctors since the 1950s and it seems to be helping many people who have COVID-19 when administered early enough. (Hydroxychloroquine is also supposedly safe and tolerable as an anti-cancer therapy.) Seems like most news sources are going out of their way to make it sound like hydroxychloroquine is the most dangerous drug in the world, but they also make it sound like it’s the greatest drug in the world for lupus and rheumatoid arthritis patients. They basically say that using hydroxychloroquine for COVID-19 patients would be taking that great and wonderful drug away from the other patients who need it. So which is it? Is hydroxychloroquine deadly or divine?

 

If you believe that a couple of Trump supporters took the medicine hydroxychloroquine and it’s President Trumps fault that the husband died, you’ve been duped. Watch this video. The wife was a prolific Democratic donor, it seems she hated her husband, she used fish tank cleaner (not the medicine hydroxychloroquine), and now she is the subject of a homicide investigation.

 

Some people claim that the reason so many news sources want to keep doctors from using hydroxychloroquine for COVID-19 is that they are desperate to keep everyone afraid to leave their homes since mail-in voting will make voter fraud much easier (the only way they could beat Trump). Others claim that the rabid anti-hydroxychloroquine campaign was to make way for the expensive new drug called remdesivir. Drug companies can’t make much money with old generic drugs, so new drugs must be pushed. Both claims could be true since remdesivir supposedly isn’t as good as hydroxychloroquine.

 

According to Dr. Shiva Ayyadurai, hydroxychloroquine does four things: (1) stops viral entry, (2) stops viral RNA replication, (3) stops viral particle assembly, and (4) stops cytokine storm. Remdesivir only stops viral RNA replication. Did you get that? Hydroxychloroquine does four things and remdesivir only does one. The doctor also said that nearly 70 percent of the people who took remdesivir had some type of adverse effect. If all of that is true and the more anemic medicine ends up being used by most doctors thanks to the smear campaign against hydroxychloroquine, the average American will beg to vote from home.

 

In case you didn’t know, Patrick Howley reported that one of the authors of the ‘study’ saying that hydroxychloroquine doesn’t work at VA hospitals got a research grant from Gilead (the company that makes remdesivir). Does that seem a little fishy to you?

 

Bryan Fischer said in an article that Dr. Fauci has known since 2005 that chloroquine is an effective inhibitor of coronaviruses. You might also want to check out the following three links:

Sequential CQ / HCQ Research Papers and Reports

 

“The Disruptive Physician” had this to say at Twitter: “Meanwhile, regular doctors like me are using HCQ + Azithromycin and Zinc to good effect. One nursing home in NE Ohio had 30 cases - started everyone on HCQ, no deaths. Quick recovery. Why would the MSM hide this? Why would twitter block people who question the WHO?” You might also want to check out Dr. Stephen Smith, Dr. Ramin Oskoui and Dr. Yvette Lozano.

 

In case you’re interested, here are a few COVID-19 patients who appear to claim that hydroxychloroquine saved their lives: elderly couple Louis Amen and Dolores Amen, Daniel Dae Kim, Rio Giardinieri, John McConnell, Margaret Novins, Jim Santilli, Billy Saracino, and Karen Whitsett (Democratic member of the Michigan House of Representatives).
