inaccessible characters?

Fri, 10 Oct 2025 01:04:56 UTC

hey so basically, on the P8SCII chart, the first row of characters (1-15) seems to be inaccessable when using chr() and there seems to be no keyboard shortcuts to type them out. anyone know anything about this?

This is a "base" cart with extra features (wow!)
Would appreciate notification of any bugs

How to set up cart:

delete all demo values (functions included)
delete the sections in the loop functions which say "delete this"
if you are using cartdata, set using_cartdata to true, and set save_menuitem to the string that you want to appear in the menu when saving
if you want to use more than 64 cartdata values, set saverange_start to the first memory address in the range subtracted by 0x8000, set saveids to how many more save groups of 64 cartdata values you need, and using_cartdata_extra to true
set game_id to your cartridge id. this will be used in cartdata functions and reloading for calibrating and recalibrating save values
set the g_init, g_update and g_draw functions to your own personal loops

optionals
there is a table called genopmt. this is an automatically prepared metatable
there is also a collection of all visible characters through characters 1-15 in the first few lines of the main _init() tab

FUNCTIONS:

-- DRAWING FUNCTIONS --

-- PRINTING FUNCTIONS --

-- MAP FUNCTIONS --

-- VALUE MODIFICATION FUNCTIONS (MATH, BOOLEANS, STRINGS) --

-- TABLE FUNCTIONS --

-- CONDITIONAL FUNCTIONS --

-- SOUND FUNCTIONS --

-- TYPE FUNCTIONS --

-- MISC FUNCTIONS --

-- PROTOTYPES --

these are functions which do not work or did not and are currently being worked on. once function is finished, final function name and type of function will be underneath the main documentation for the function.

Any more features I should add?

almost unlimited cartdata

Sat, 20 Sep 2025 08:37:18 UTC

okay so basically this trick almost gives you infinite savedata

first, choose a memory address above 0x7fff to represent a progress counter, a memory address above 0x7fff to represent if the game has already set the progress counter to 0, a memory address above 0x7fff to represent the progress before updating, a memory address to declare if the game has started, a variable declaring if the game is calibrating the save values, and a variable inside the game declaring how many extra groups of 64 savedata values are required.

second, in the _init function, set the initial progress counter to the actual progress counter. make an if statement which checks if the progress counter is equal or over the limit. inside that statement, run cartdata with an id concatenated with the progress, set a group of memory addresses to the cartdata values, change the progress counter by one by using the initial progress counter, and then finally load the cartridge again.

third, in the _update function, add an if statement which checks if the game has started. move all of the previous code inside of the _update function into that statement.

your code by now should look something like this:

function calibrate_save(index)
 for i=0,63 do
  poke(0x8000+index*0x40+i+range_start,dget(i))
 end
end

--0xffff=calibration progress
--0xfffe=pre-updated calibration progress
--0xfffd=if has set initial calibration
--0xfffc=if has started game

function _init()
 is_calibrating=false
 saveids=4
 range_start=0x0000
 if peek(0xfffd)!=1 then
  poke(0xffff,0)
  poke(0xfffd,1)
 end
 poke(0xfffe,peek(0xffff))
 if peek(0xffff)<saveids then
  is_calibrating=true
  cartdata("mygameid_decomp" .. peek(0xffff))
  calibrate_save(peek(0xffff))
  poke(0xffff,peek(0xfffe))
  load("mygame.p8" or "#mygame")
 end
end

function _update()
 if not is_calibrating then
  -- ...
 end
end

all this does is use a different cartdata id for each initial runtime moment, then restarts if the values have been set, and if they have to be set.

to access the save data values, get the designated memory address within the group of memory addresses.

to save from within the game, you need to make a menuitem, which basically does the same exact thing when it calibrates the values at the start, except instead of the addresses being set, the save values are set by the addresses e.g:

--0xfffb=if is saving
function _init()
 is_calibrating=false
 saveids=4
 range_start=0x0000
 if peek(0xfffd)!=1 then
  poke(0xffff,0)
  poke(0xfffb,0)
  poke(0xfffd,1)
 end
 poke(0xfffe,peek(0xffff))
 if peek(0xffff)>=saveids then
  poke(0xfffb,0)
 end
 if peek(0xfffb)==1 then
  cartdata("mygameid_decomp" .. peek(0xffff))
  save(peek(0xffff))
  load("mygame.p8" or "#mygame")
 end
 if peek(0xffff)<saveids and peek(0xfffb)!=1 then
  is_calibrating=true
  cartdata("mygameid_decomp" .. peek(0xffff))
  calibrate_save(peek(0xffff))
  poke(0xffff,peek(0xfffe))
  load("mygame.p8" or "#mygame")
 end
end

function save(index)
 for i=0,63 do
  dset(i,peek(0x8000+i+range_start+index*0x40))
 end
end

function _update()
 if not is_calibrating then
  menuitem(1,"save",function()
   poke(0xffff,0)
   poke(0xfffb,1)
   load("mygame.p8" or "#mygame")
  end)
  --...
 end
end

just another minor exploit :)

playing music notes from "print()"

Sat, 20 Sep 2025 06:01:17 UTC

this method exists which almost no information is spread about on the internet

all you have to do is print "\A" concatenated with the note, and then the octave e.g:print("\AD#3"). this plays the D# note on the third octave you can also print a message as it plays if you concatenate the string with a space, and then the message e.g:print("\AD#2 Hello World!"). one thing i find really cool about this feature is that you can harmonize notes by concatenating multiple notes by a space e.g:print("\AD#3 \AD2 \AD1 \AC#1 \AD0").

"supposedly new" cc techs

Thu, 28 Aug 2025 12:42:55 UTC

hey so i've come to the realisation that as i continue to work on new celeste mods, i am most likely going to come across alot more techs which i am not familiar with, so i guess this post can be like an area for creating cc techs and verifying which cc techs already existed.

-- dash trajectory manipulation --

the logic of this tech is pretty strange so prepare yourselves
anyway basically what i mean by "dash trajectory manipulation", is changing the direction of your dash midway through the dash itself
i don't really know how it works
i was just kinda messing around and then i got this
| | | | | | | | | | | | | | | | | | | | | | | | | |
V V V V V V V V V V V V V V V V V V V V V V V V V V

i think i was turning around as soon as i got to the edge of the screen, then performing the spike walk.
for some reason it only works on the edges of the screen tho?
anyone know anything about this?

-- vertical movement manipulation --

ok so this one is crazu

so basically in order to pass this level, you have to dash horizontally, jump on the next frame which you can, and then dash horizontally on the next frame.

what's happening?

so basically when you dash horizontally the first time and jump, because you leave the dash early, the game assumes that you haven't left the dash yet, and slows down the movement on the y axis, offsetting you on the y axis by 2 pixels on the next frame, which allows you to dash on the one pixel that's safe.

hopefully this gives you some insight as to how to beat this thing:

better cprint function

Sun, 24 Aug 2025 12:18:29 UTC

hey so i've seen a lot of carts which have a function for printing a string of text in the centre of the area on the x axis which they have depicted, and it often ends up looking something like this:

-- actual function
function cprint(txt,centre,y,c)
 print(txt,centre-#txt*2,y,c)
end

-- example
function _init()
 cls()
end

function _draw()
 cprint("Centre:64",64,0,7)
 for x=0,127,8 do
  for y=16,127,8 do
   line(x,0,x,127,8)
   line(0,y,127,0,8)
  end
 end
 cprint("Hello World!",64,62,7)
end

but often one thing that they don't account for is the extra space in which the characters with an id over 127 cover. for example,

-- chr(151)
cprint("❎❎❎❎❎❎❎",64,62,7)
cprint("❎❎❎❎❎❎",64,68,7)
cprint("❎❎❎❎",64,74,7)

in order to fix this, i first built a function which returns how many characters in the string are doubled in length,

function has_double(str)
 local letters=0
 for i=1,#str do
  local char_code=ord(sub(str,i,i))
  if char_code>=128 and char_code<=255 then
   letters+=1
  end
 end
 return letters
end

then i implemented it into the "cprint" function as so

function cprint(txt,centre,y,c)
 for i=1,#txt do
  local added_letters=has_double(txt)
  print(text,centre-(#txt+added_letters)*2,y,c)
 end
end

new cc tech?

Sun, 17 Aug 2025 04:28:30 UTC

hey so i think i just found a new tech

basically, from what i can see, the player falls down, and with enough precision and velocity in which the player falls, there is a one-frame window where you can jump off of the wall with the spikes
this just stood out to me because the hitbox of a right-facing spike is larger than a left-facing spike's hitbox. This allows the player to jump off of a left-facing spike's wall while stationary, but not with a right-facing spike's.
maybe this was already a tech?
