Secretum Labyrinth has been using the RAM under the OS, but it is not too hard to turn the OS back on, just would need to set pages 0,2,3. Page 4 and up are being used by the game. So having DOS loaded in probably mess things up really bad.
I stated I am considering XBIOS as a possible option to save progress to disk. Issues with XBIOS, it does not have the ability to create new files, so the disk will need to pre populated with blank files to save to. Also considering it for other functions like alternate RMT music or fonts. Another way to save game progress is put the game on a flash cart and have an unused bank for saving game files. I have the subroutines to flash to several different types of flash cartridges, but most likely be AtariMax flash cart.
As far as I am aware of XBIOS is not owned by any particular person or is under copyright, and looks like something anybody could had came up with. I can always alter it also, omit the portions I do not need, etc.
I never bought anything up piracy here or stated anything about it awhile, so please it is useless to keep re-hashing old subjects. I am not the only one with concerns about it.
I have been looking at how well people sold their games through other software house and on other media. Looking to see if there is anything I could be doing better. People been telling over the years I "WILL" do better if I did this or that, and now been finding out it would not had made much difference. However, Video 61 started laminating instruction sheets, using a protective clam shell with labels on them, and putting a clear coating over the cartridge labels. I understand a few people had 200-500 printed boxes, instruction manuals, glossy labels for the disk or cartridge, made up and spending good chunk of money. Then only sell less than a quarter units they had hoped for. I would not do anything have more than 100 of anything made.
