Thank You very much... Indeed it worked. "machine=tandy" BASIC.COM with BASICA.EXE (GW-BASIC for Tandy).

Thank You! I definitely will try it. I didn't know that there was a version of GW-BASIC for the Tandy. And also, less that it supports the 3-voice play command. I appreciated.

Does 123B.JRC starts (after the header at 200h) with the following hex code "00 00 00 18 00 28 00 30 FF FF..." ??? Or I got a corrupted dump?

DOSBox does support two cartridges, and you can run Lotus 1-2-3 with the command: boot 123A.JRC 123B.JRC -e 123 I try this but it hangs after opening the 123B.JRC... ColorPaint runs as you said, it becomes unstable.

I'll try MESS emu, as our friend mentioned (Thank you BTW) to see if does the trick. But this will take some time, so I'll get back to ye all later. 😀

OK! Tand-Em will not work with BASIC Cartridge because that cart. needs the BASIC BIOS of the PCjr. So, I guess that it won't work either with DOSBox. I'm thinking about GW-BASIC, but I guess that it doesn't have the 3-voice sound function for the support of PLAY Statement (e.g. PLAY "CDEF", "CEA"). …

Does someone have used PCjr BASICA Cartridge for DOSBox and running DOS 2.x to access BASIC with thy intention to use the 3 voices function thru the PLAY statement (for using chords)? I have fix the BASIC Cartridge header (512) with the offset ROM start E8 at 0x1CE, BUT I can't access either the …

Thank you very much for the instructions. I quite follow really well except that I had my doubt on the begging of the code that I had hex: 55 AA, instead of EE AA. At the very last instruction, when said to insert the game code again; I didn't know that you were referring to the same beginning of …

Thank you! It working fine. I'll like to try Microsurgeon, but the last post of this game is that Offset of the segment to the start of the ROM is E600:0000 but what I could understand is that the code has a mirroring effect which the binary file dump needed to be appended some extra bytes (null …

The mapper mods has been done and game has been responded well. But the firing-ship tends to move automatically to the right without pressing any key. It actually goes to the left if I press the left key until I stop holding it. Which, again, drifts to the right by itself. Can I calibrate or …

As in the config: usescancodes=true ... and... timed=true ..and... joysticktype=auto ... How can I use keymapper to assign the cursors keys without a physical joystick? I also tried to bind the cursors keys to act as a joystick but do not know the scancodes in the mapper file. (e.g.: key_up "key 273 …

Okay... following the nerdy terms and the comments that our past friends left us. I could manage to run the Demon Attack cartridge dump to a fix of the "damnated" header (pushing the code at 513 bytes location) and the editing to write the tiny byte "E6" at the 462 length byte location that was need …
