they are not 🙂 thats why you cant find them in ram ...

 

seteg is actually a command in the G7400 Basic (16KB, written in Z80 code) that instructs the cart stuck into the G7400 (2 KB, written in 8048h code) to redefine a character on the EF9340+EF9341 chips (special chips in the G7400 not present in the G7000, that were also used in various teletext systems) - so no simple poke to set the characters 🙂 you could disassemble the C7420 Rom Source to see what exactly seteg is doing and it might be possible to write a machine language program in Z80 code you could poke into memory and run - but I doubt it would give you a speed advantage over seteg ... 

 

also - not really worth scanning the memory from -32767 to 32767 - the C7420 has only 16KB of ram 🙂

is there an annotated rom disassembly somewhere online?

 

i actually wrote a program that sticks numbers straight into the basic code but i would like to do it the other way

[videopac g7400 c7420 character memory locations]

very little seems to be written about this system. i was wondering where the user definable characters were stored in ram? so i could change them with a poke, instead of using the cumbersome seteg command. i tried running a program to peek the memory from -32767 to 32767, looking for 10 identical numbers that i had written in seteg, to no avail. any help would be appreciated

[is there a way of copying and pasting into an emulator? im using compumate...]

are there any emulators that do this? i want to insert some programs i have found for it. ive tried loading and saving things into basic but stella doesnt seem to accept tapes and i cant get compumate to work in mame. any ideas?

[not enough space for dimensional arrays in famicom basic using mmc5 mod]

stupidly i didnt see that there was a paste function in the familybasic emulator by TAKEDA, toshiya. anyway now i have a problem with dimensional arrays. if i try and add more than 63 dimensional strings, it gives me a ov error. its not running out of memory but i think its not using all the extra ram for variables. is there a way around this? like moving the ramtop or basic allocation space, etc? say, with a poke? ive noticed that if there is no program in the memory, this problem doesnt happen

[familybasic by TAKEDA toshiya]

it allows 16k in basic but i cant find a way of pasting a program into it or using another program to paste into it, to save it on a format that it recognizes. the 16k basic is developed by Mr.Makimura. http://rdev.php.xdomain.jp/makimura/archive/family-basic. any help would be appreciated...

I saw an article somewhere about expanding the RAM in the BASIC cartridge up to 24K, not sure if the mod was for the 2K or the 4K release.

Deleting REM statements and using reusable subroutines can also help maximize Memory in large programs.

 

i have got something to work, i found it by accident. its called familybasic by TAKEDA toshiya. it allows 16k in basic but i cant find a way of pasting a program into it or using another program to paste into it, to save it on a format that it recognizes. the 16k basic is developed by Mr.Makimura. http://rdev.php.xdomain.jp/makimura/archive/family-basic

thank you

I'm not sure about physically adding more RAM to the cart, but could you modify the BASIC rom itself and expand the amount of RAM when run in an emulator or from a flash cart?  I run FB from my PowerPak and imagine that image could be hacked somehow.

thanks

[nintaco .tape file format]

i dont really understand this format. it doesnt seem to be compatible with any other emulator, like virtual nes or fceux. i know its a proprietary file format but could it be converted to wav or a cas file? any help would be welcome

[does anyone have a copy of famicom dos (BBGDOS) ?]

apparently according to the website it can use the famicom disk system to run a dos system and even a gui. any help will be welcome...

[is there a way of adding more ram to famicom basic?]

would love to know how

[is there a way of adding more ram to famicom basic?]

4k just isnt enough. ive seen projects online that do this in hardware. could it be done? and if so, how? i imagine it would be a case of changing some of the assembly code to point to a larger location in memory. i.e by making the cart bigger? any help would be welcomed. 

[is there an emulator for the sharp mz 700 that allows you to copy and paste?]

ive managed to get it to open but it just sits there beeping at me with blue stripes on the screen. as there are no help files or instructions for it i dont know what to do.

 

*there seem to be some instructions online but they dont really help

Can't check it right now; but Yoshida Takeda's emulators usually allow this feature: Common Source Code Project

 

Look for EmuZ-700...

thank you. unfortunately that link doesnt work. and i cant find that exact emulator on google

[is there an emulator for the sharp mz 700 that allows you to copy and paste?]

i want to copy and paste a program out of basic into notepad, etc. ive only managed to get one emulator to work and this doesnt do it. any help would be appreciated. ive tried the sharp mz forum but it wont let me register for some reason, so i cant ask on there...

Maybe explain what you're up to more precisely as I don't quite get what you're up to there.... and it has only been 12 hours on AtariAge (this isn't VideoGameSage which has much of the old NintendoAge membership that may better know.)

i want to copy a program from say notepad and then paste it into an nes emulator. so i dont have to type out huge listings. this can be done on c64, bbc and other emulators i have used. 

[is there a way of pasting a program into any nes emulator with famicom basic?]

really? no one?

[is there a way of pasting a program into any nes emulator with famicom basic?]

ive tried a few but they dont seem to have this functionality. i also tried mame but i cant get it to boot. also with a google search there doesnt seem to be any third party programs that will convert text to a wav or tape file. any help would be appreciated.

 

 

[does anyone have a ti99 motherboard for sale?]

i want it to try and do the 16 bit 32k mod on. without potentially destroying my own motherboard. although i do have experience with soldering and electronics, i dont want to risk my working ti99. 

[how many graphics modes can you have in a display list?]

i wanted to know if you could use the same mode over and over, so you could have a different set of 5 colours on say every 8 lines, using antic mode 4. and how may times you could do this

[how many graphics modes can you have in a display list?]

im talking about using the same graphics mode over and over if that is possible

[how many graphics modes can you have in a display list?]

and im guessing you can have a different set of colours for each mode? say if i was using antic mode 4 (graphics mode 12) every time?

[atari 8 bit multicolor sprites]

ive been playing around with antic mode 4 but realize that it only has 4 colors, so i guess any character based sprites will not work if i want sprites to have different sets of 4 colors? 

[atari 8 bit multicolor sprites]

how is this done? im guessing sprite overlaying but is there a quicker/easier way? i.e in software? as overlaying more than 1 sprite with 4 colours would involve multiplexing, no?
