New page

'''This original version of this [http://www.atariage.com/forums/topic/153704-ti-994a-development-resources/ page] is located at the Atariage game programming subgroup.'''

This page gives an overview of resources that may be useful if you intend to write software for the TI-99/4A.


'''If you are the owner of one of the programs or sites and do not want it posted, please let me know and it will be removed immediately.''' 
'''Also if you think a reference to an important development resource is missing, then please let me know and I'll be happy to add to the list.'''

: Convert almost any E/A#5 program memory image to a GROM cartridge for emulation.
: A version that will convert a E/A#5 program image to ROM cartridge is planned.
: Note that you need 32K memory expansion for running the E/A#5 program stored in the cartridge image.
: Status: '''Still under active development'''

'''2. File transfer'''
