Classic99 runs most stuff fine: System ROMs and many cartridges are INCLUDED under license from Texas Instruments. Classic99 is a open source Texas Instruments TI99/4A emulator for Windows 2000 and up. Device emulation To enable chromes device emulation, its possible to send.Description. Now it's been ported to Linux and Mac OS X and more features are still being added.This post will cover installation and running the script on either Mac OS or. Later, it was ported to Windows and had sound support added. Then it was ported to OS/2 and graphics support for the OS/2 Presentation Manager was added.'TI-99/4A BASIC' (ti99basic) is a version of Texas Instruments' BASIC as found in ROM on the TI-99/4A. If you're interested in writing documentation, let me know.Download TI-99/4A BASIC for free. Most modules seem to work fine.DISCLAIMER: I'm not one for writing a lot of documentation, so you're encouraged to look at the code to see how some things work if they're not described here.Getting StartedInstalling the emulator is easy. In order to get a working installation, you should run the included setup script which will create the required files. Texas Instruments will not allow these to be distributed, so they are not included with ti99sim.
Under Windows, the search is limited to the current directory followed by the directory specified in the environment variable HOME (if it is defined at all). When loading files (ROMs, cartridges, disk images, …), ti99sim will look in the current directory, ~/.ti99sim, and finally, /opt/ti99sim. In addition to installing the binaries, symbolic links to them will be created in /usr/local/bin (which should already be in your path). The default directory is /opt/ti99sim and the binaries will be installed in /opt/ti99sim/bin. Without it, the emulator will not do anything useful. This ROM cartridge contains the operating system, the BASIC interpreter, and a description of the RAM configuration for the computer. This section describes how to create and install your console ROM files by hand if you prefer to do it yourself.Once you have run make install, you will need to create the console ROM cartridge TI-994A.ctg (see convert-ctg below for instructions) in order to run the emulator. The Console ROM & CartridgesNOTE: Since v0.14.0, the setup script found in the scripts folder is provided to help create a set of both console & cartridge files to get you started. If there is no logical directory for a given file, only the base directory will be searched. Finally, disks can be either single-sided or double-sided. These drive could be either single-density (using FM encoding) or high-density (using MFM encoding). Depending on your disk controller, the TI could access either 3 or 4 floppy drives. This section deals with floppy disks. In order to get up and running, however, the only file needed is the TI-994A.ctg file.│ ├─ DISKASSM - Miller Graphics' Disk-Assembler│ ├─ image.cf7 - Fle accessed by CF7+ module│ └─ MG_DIAG - Miller Graphics' Advanced Diagnostics├─ Gram Kracker.ctg - Miller Graphic's Gram Kracker ROMs├─ spchrom.bin - TI Speech Synthesizer ROM├─ ti-disk.ctg - TI ROM DSR module for disk access└─ TI-994A.ctg - TI-99/4A ROM Up and RunningWhat good is a computer is you can't save information or programs? On the TI-99/4A, there are two standard storage media: floppy disks and cassette tapes. If you don't have this file, you can use mkspch to create one that will keep the emulator happy.If you want to use the disk emulation features, you will need to create another cartridge named ti-disk.ctg that contains a copy of the TI Disk Controller ROM (the section on convert-ctg contains information about creating cartridges for peripheral DSR ROMs).In order to use the CF7+ disk emulation features, you will need to create a cartridge named cf7+.ctg using the supplied cf7+.dat file.A sample installation is shown below. To get around this, disks are read (using special programs, usually written for MS-DOS, to get easy access to the disk) and converted to a single file on the local hard drive. In addition, modern operating system don't make it easy to access the disk at the level required to read TI disks. The disk utility is able to read and write to these devices.The problem with emulating the TI (besides finding a 5¼ʺ disk drive) on an IBM PC is that most PC's don't easily allow single-density (FM) disks to be read. Ti 99 Emulator Archive File IsTI-99/4A Emulator Disk Formats NameRetains sector ordering and special formatting informationUnable to distinguish between SSDD & DSSD disksHard to parse. One way of looking at an archive file is as a cross between a file and a disk (in fact, the disk and other utilities treat these files as disks). Each file stored in the archive contains all the information to completely recover the original file including the file descriptor record. Archive files were developed by Barry Boone and use a Limpel-Zev compression scheme similar to. The formats that I'm aware of, all of which are supported by TI-99/Sim, are shown in table below.In addition to supporting disk images, TI-99/Sim also supports archive files. This format allows the emulator to identify all of the attributes of the original file. The most common format for v9t9 systems is the FIAD format. As with disks, there are a few different formats that individual files may use. However, there are reasons to deal with individual files rather than entire disks. Lots of extra data (roughly double PC99's format)TI-99/Sim only deals with files contained within disk images. Ableton live trial for macThe difference is limited to the 128 byte header. The actual file descriptor record from the file is included in the header of the file, followed by the raw sectors that make up the file.Very similar to FIAD in structure. TI-99/4A File Formats FormatV9t9's native file format. When this format is used, the TI file is converted, as best as possible, to a native file on the host operating system. Finally, files can be stored as 'native' files. This is the format used to transfer files to/from the TI using the X-Modem protocol. To access either a FIAD or TIFILES files, simply use the name of the file on the host filesystem. These files can be either standalone files or files contained within a disk. Each flavor includes most or all of the information normally found in the file descriptor record (the original name is not always present).This format has no header or formatting information.Two of the utility applications, dumpcpu and list, access files. Photoshop 5 for mac downloadA set of sample files, TI-994A.dat, Mini-Memory.dat, and Gram Kracker.dat, located in the roms directory, are supplied as examples of the format of the hex dump file. It will convert your existing v9t9 ROMs or create cartridges using output from a hex dump of a ROM image. The convert-ctg program allows you to create these cartridges. Ctg files to store the ROM and/or GROM images contained within the computer console and plug-in cartridges. For example, to list a BASIC program called GAME on a disk named sample.dsk the syntax would be: list sample.dsk:GAME Included ProgramsThe ti99sim emulator uses special. For example, the following command will convert the files PARSECC.BIN and PARSECG.BIN to PARSEC.ctg:Convert-ctg / your-path-here/v9t9/v6.0/modules/PARSEC.BINFiles to be converted can be in any directory. Convert-ctg understands the naming conventions used by present and past versions of v9t9, and will attempt to determine which version of files that you have installed. The base name is usually the portion of the filenames that are common between all files associated with a particular cartridge.
