Once you've uploaded the ROM, you have to convert it using the

<p>To do that, start a Command Prompt while running Windows, and

type:</p>
|
||||
<blockquote>Convert <rom-file> ROM.38G</blockquote>
|

<p>Where <rom-file> is the path to your ROM image. This will

create a file named ROM.38G. This tool will also check its validity.

|

Once you've uploaded the ROM, you have to convert it using the Rom2emu utility.
|

</p>
|

<p>To do that, start a Command Prompt while running Windows, and
|

type:</p>
|

<blockquote>Rom2emu <rom-file> ROM.39G</blockquote>

<p>There's also a HP39G/HP40G beta ROM for emulators inside an old

<p>If you have already used another HP48 emulator, you can convert

the ROM using the Convert utility.

|

<p>To do that, start a Command Prompt while running Windows, and

type:</p>

<blockquote>Convert <rom-file> ROM.48G</blockquote>
|

<p>or</p>
|
||||
<blockquote>Convert <rom-file> ROM.48S</blockquote>
|

<p>Where <rom-file> is the path to your old ROM image. This
|
||||
will create a file named ROM.48G or ROM.48S, depending on the version
|
||||
you own. This tool should be able to read any style of ROM image, and
|
||||
will also check its validity. Note that if you run it with only one
|
||||
parameter, no file will be written, but it will still check the
|
||||
validity of the ROM.</p>
|

<p>If you have never used an HP48 emulator, and don't have a ROM
|

dump, you can either use Jean-Yves Avenard's ROMUPL.BIN or the
|
||||
ROMDump Wizard V1.x, which will almost automatically get the ROM from
|

your HP48. After the download you may have to convert your dump with

the CONVERT utility into the Emu48 format.</p>

Service Pack 65 for Emu48 Version 1.0
|
||||
|
||||
EMU48.C
|
||||
- changed function SettingsPeripheralProc(), get the COM port state
|
||||
over function CommIsOpen() now
|
||||
- changed function SaveChanges(), added document name to MRU list
|
||||
- changed function OnFileMruOpen(), modified implementation taking
|
||||
care of the SaveChanges() modification adding a filename to the
|
||||
MRU list after saving a document
|
||||
|
||||
EMU48.H
|
||||
- changed function prototype
|
||||
- extern declaration of global functions
|
||||
- removed extern declaration of global variable
|
||||
|
||||
EMU48.RC
|
||||
- changed version and copyright
|
||||
|
||||
ENGINE.C
|
||||
- removed global variable bCommInit
|
||||
- changed function CheckSerial(), get the COM port state over
|
||||
function CommIsOpen() now
|
||||
- changed function WorkerThread(), removed bCommInit setting
|
||||
|
||||
FILES.C
|
||||
- changed function DibNumColors(), CreateBIPalette() and
|
||||
DecodeBmp(), marked BITMAPINFOHEADER pointer as unaligned
|
||||
- changed function CreateBIPalette() and DecodeBmp(), minor
|
||||
optimization at input data check
|
||||
- changed function DecodePng(), simplified destination row pointer
|
||||
calculation in main loop and removed dead code in function
|
||||
cleanup
|
||||
|
||||
LODEPNG.C
|
||||
- changed implementation file to LodePNG version 20220717 with
|
||||
unmarked typecast patches for x64 compatibility, Copyright (c)
|
||||
2005-2022 Lode Vandevenne
|
||||
|
||||
LODEPNG.H
|
||||
- changed header file to LodePNG version 20220717
|
||||
|
||||
MOPS.C
|
||||
- bugfix in function ReadIO(), the RBF (Receive Buffer Full) bit was
|
||||
cleared before the content of the RBR LSB (0x114) and RBR MSB
|
||||
(0x115) register was read, so the serial port event thread
|
||||
overwrote the RBR register with new data in some conditions
|
||||
- bugfix in function WriteIO(), fixed implementation of the EIRU
|
||||
bit in the IRC (0x11A) register
|
||||
|
||||
MRU.C
|
||||
- added some remarks
|
||||
- added function MruID(), return ID of the given entry
|
||||
- changed function MruFilename(), changed function interface writing
|
||||
found filename into a buffer instead of returning a pointer to the
|
||||
filename
|
||||
|
||||
PCH.H
|
||||
- added __unaligned definition for MSVC6.0 SDK and earlier
|
||||
|
||||
SERIAL.C
|
||||
- added new function CommIsOpen(), return if COM port open
|
||||
- bugfix in function CommReceive(), the ReadFile() buffer argument
|
||||
was a BYTE** instead of a BYTE* (the wrong argument type was fixed
|
||||
by the compiler)

sBIT chunk: significant bits. Optional metadata, only set this if needed.
|

|
||||
If defined, these values give the bit depth of the original data. Since PNG only stores 1, 2, 4, 8 or 16-bit
|
||||
per channel data, the significant bits value can be used to indicate the original encoded data has another
|
||||
sample depth, such as 10 or 12.
|
||||
|
||||
Encoders using this value, when storing the pixel data, should use the most significant bits
|
||||
of the data to store the original bits, and use a good sample depth scaling method such as
|
||||
"left bit replication" to fill in the least significant bits, rather than fill zeroes.
|
||||
|
||||
Decoders using this value, if able to work with data that's e.g. 10-bit or 12-bit, should right
|
||||
shift the data to go back to the original bit depth, but decoders are also allowed to ignore
|
||||
sbit and work e.g. with the 8-bit or 16-bit data from the PNG directly, since thanks
|
||||
to the encoder contract, the values encoded in PNG are in valid range for the PNG bit depth.
|
||||
|
||||
For grayscale images, sbit_g and sbit_b are not used, and for images that don't use color
|
||||
type RGBA or grayscale+alpha, sbit_a is not used (it's not used even for palette images with
|
||||
translucent palette values, or images with color key). The values that are used must be
|
||||
greater than zero and smaller than or equal to the PNG bit depth.
|
||||
|
||||
The color type from the header in the PNG image defines these used and unused fields: if
|
||||
decoding with a color mode conversion, such as always decoding to RGBA, this metadata still
|
||||
only uses the color type of the original PNG, and may e.g. lack the alpha channel info
|
||||
if the PNG was RGB. When encoding with auto_convert (as well as without), also always the
|
||||
color model defined in info_png.color determines this.
|
||||
|
||||
NOTE: enabling sbit can hurt compression, because the encoder can then not always use
|
||||
auto_convert to choose a more optimal color mode for the data, because the PNG format has
|
||||
strict requirements for the allowed sbit values in combination with color modes.
|
||||
For example, setting these fields to 10-bit will force the encoder to keep using a 16-bit per channel
|
||||
color mode, even if the pixel data would in fact fit in a more efficient 8-bit mode.
